[3.13] gh-113993: Allow interned strings to be mortal, and fix related issues (GH...

* Add an InternalDocs file describing how interning should work and how to use it.

* Add internal functions to *explicitly* request what kind of interning is done:
  - `_PyUnicode_InternMortal`
  - `_PyUnicode_InternImmortal`
  - `_PyUnicode_InternStatic`

* Switch uses of `PyUnicode_InternInPlace` to those.

* Disallow using `_Py_SetImmortal` on strings directly.
  You should use `_PyUnicode_InternImmortal` instead:
  - Strings should be interned before immortalization, otherwise you're possibly
    interning a immortalizing copy.
  - `_Py_SetImmortal` doesn't handle the `SSTATE_INTERNED_MORTAL` to
    `SSTATE_INTERNED_IMMORTAL` update, and those flags can't be changed in
    backports, as they are now part of public API and version-specific ABI.

* Add private `_only_immortal` argument for `sys.getunicodeinternedsize`, used in refleak test machinery.

* Make sure the statically allocated string singletons are unique. This means these sets are now disjoint:
  - `_Py_ID`
  - `_Py_STR` (including the empty string)
  - one-character latin-1 singletons

  Now, when you intern a singleton, that exact singleton will be interned.

* Add a `_Py_LATIN1_CHR` macro, use it instead of `_Py_ID`/`_Py_STR` for one-character latin-1 singletons everywhere (including Clinic).

* Intern `_Py_STR` singletons at startup.

* For free-threaded builds, intern `_Py_LATIN1_CHR` singletons at startup.

* Beef up the tests. Cover internal details (marked with `@cpython_only`).

* Add lots of assertions

+# String interning
+
+*Interned* strings are conceptually part of an interpreter-global
+*set* of interned strings, meaning that:
+- no two interned strings have the same content (across an interpreter);
+- two interned strings can be safely compared using pointer equality
+  (Python `is`).
+
+This is used to optimize dict and attribute lookups, among other things.
+
+Python uses three different mechanisms to intern strings:
+
+- Singleton strings marked in C source with `_Py_STR` and `_Py_ID` macros.
+  These are statically allocated, and collected using `make regen-global-objects`
+  (`Tools/build/generate_global_objects.py`), which generates code
+  for declaration, initialization and finalization.
+
+  The difference between the two kinds is not important. (A `_Py_ID` string is
+  a valid C name, with which we can refer to it; a `_Py_STR` may e.g. contain
+  non-identifier characters, so it needs a separate C-compatible name.)
+
+  The empty string is in this category (as `_Py_STR(empty)`).
+
+  These singletons are interned in a runtime-global lookup table,
+  `_PyRuntime.cached_objects.interned_strings` (`INTERNED_STRINGS`),
+  at runtime initialization.
+
+- The 256 possible one-character latin-1 strings are singletons,
+  which can be retrieved with `_Py_LATIN1_CHR(c)`, are stored in runtime-global
+  arrays, `_PyRuntime.static_objects.strings.ascii` and
+  `_PyRuntime.static_objects.strings.latin1`.
+
+  These are NOT interned at startup in the normal build.
+  In the free-threaded build, they are; this avoids modifying the
+  global lookup table after threads are started.
+
+  Interning a one-char latin-1 string will always intern the corresponding
+  singleton.
+
+- All other strings are allocated dynamically, and have their
+  `_PyUnicode_STATE(s).statically_allocated` flag set to zero.
+  When interned, such strings are added to an interpreter-wide dict,
+  `PyInterpreterState.cached_objects.interned_strings`.
+
+  The key and value of each entry in this dict reference the same object.
+
+The three sets of singletons (`_Py_STR`, `_Py_ID`, `_Py_LATIN1_CHR`)
+are disjoint.
+If you have such a singleton, it (and no other copy) will be interned.
+
+
+## Immortality and reference counting
+
+Invariant: Every immortal string is interned, *except* the one-char latin-1
+singletons (which might but might not be interned).
+
+In practice, this means that you must not use `_Py_SetImmortal` on
+a string. (If you know it's already immortal, don't immortalize it;
+if you know it's not interned you might be immortalizing a redundant copy;
+if it's interned and mortal it needs extra processing in
+`_PyUnicode_InternImmortal`.)
+
+The converse is not true: interned strings can be mortal.
+For mortal interned strings:
+- the 2 references from the interned dict (key & value) are excluded from
+  their refcount
+- the deallocator (`unicode_dealloc`) removes the string from the interned dict
+- at shutdown, when the interned dict is cleared, the references are added back
+
+As with any type, you should only immortalize strings that will live until
+interpreter shutdown.
+We currently also immortalize strings contained in code objects and similar,
+specifically in the compiler and in `marshal`.
+These are “close enough” to immortal: even in use cases like hot reloading
+or `eval`-ing user input, the number of distinct identifiers and string
+constants expected to stay low.
+
+
+## Internal API
+
+We have the following *internal* API for interning:
+
+- `_PyUnicode_InternMortal`: just intern the string
+- `_PyUnicode_InternImmortal`: intern, and immortalize the result
+- `_PyUnicode_InternStatic`: intern a static singleton (`_Py_STR`, `_Py_ID`
+  or one-byte). Not for general use.
+
+All take an interpreter state, and a pointer to a `PyObject*` which they
+modify in place.
+
+The functions take ownership of (“steal”) the reference to their argument,
+and update the argument with a *new* reference.
+This means:
+- They're “reference neutral”.
+- They must not be called with a borrowed reference.
+
+
+## State
+
+The intern state (retrieved by `PyUnicode_CHECK_INTERNED(s)`;
+stored in `_PyUnicode_STATE(s).interned`) can be:
+
+- `SSTATE_NOT_INTERNED` (defined as 0, which is useful in a boolean context)
+- `SSTATE_INTERNED_MORTAL` (1)
+- `SSTATE_INTERNED_IMMORTAL` (2)
+- `SSTATE_INTERNED_IMMORTAL_STATIC` (3)
+
+The valid transitions between these states are:
+
+- For dynamically allocated strings:
+
+  - 0 -> 1 (`_PyUnicode_InternMortal`)
+  - 1 -> 2 or 0 -> 2 (`_PyUnicode_InternImmortal`)
+
