gh-139871: Add `bytearray.take_bytes([n])` to efficiently extract `bytes` (GH-140128)

Update `bytearray` to contain a `bytes` and provide a zero-copy path to
"extract" the `bytes`. This allows making several code paths more efficient.

This does not move any codepaths to make use of this new API. The documentation
changes include common code patterns which can be made more efficient with
this API.

When just changing `bytearray` to contain `bytes` I ran pyperformance on a
`--with-lto --enable-optimizations --with-static-libpython` build and don't see
any major speedups or slowdowns with this; all seems to be in the noise of
my machine (Generally changes under 5% or benchmarks that don't touch
bytes/bytearray).

This splits the OS API specific functionality to get the number of threads out
from the fallback Python method and warning raising code itself.  This way the
OS APIs can be queried before we've run
`os.register_at_fork(after_in_parent=...)` registered functions which
themselves may (re)start threads that would otherwise be detected.

This is best effort.  If the OS APIs are either unavailable or fail, the
warning generating code still falls back to looking at the Python threading
state after the CPython interpreter world has been restarted and the
after_in_parent calls have been made.  The common case for most Linux and macOS
environments should work today.

This also lines up with the existing TODO refactoring, we may choose to expose
this API to get the number of OS threads in the `os` module in the future.
