cmake: disable unity mode with Windows Unicode + TrackMemory
"TrackMemory" is `ENABLE_DEBUG=ON` (aka `ENABLE_CURLDEBUG=ON`,
aka `-DCURLDEBUG`).
There is an issue with memory tracking and Unicode when built in "unity"
mode, which results in the curl tool crashing right on startup, even
without any command-line option. Interestingly this doesn't happen under
WINE (at least on the system I tested this on), but consistenly happens
on real Windows machines. Crash is 0xC0000374 heap corruption. Both
shared and static curl executables are affected.
This limitation probably won't hit too many people, but it remains
a TODO to find and fix the root cause and drop this workaround.

appveyor: rewrite batch in PowerShell + CI improvements
1. Rewrite in PowerShell:
- rewrite MS-DOS batch build script in PowerShell.
- move some bash operations into native PowerShell.
- fixups for PowerShell insisting on failure when a command outputs
something to stderr.
- fix to actually run `curl -V` after every build.
(and exclude ARM64 builds.)
- also say why we skipped `curl -V` if we had to skip.
- fix CMake warnings about unused configuration variables, by adapting
these dynamically for build cases.
- dedupe OpenSSL path into a variable.
- disable `test1451` failing with a warning anyway due to missing python
impacket. (after trying and failing to install impacket)
PowerShell promotes these warnings to errors by PowerShell. We can also
suppress they wholesale if they start causing issues in the future,
like we already to with `autoreconf` and `./configure`.
PowerShell is better than MS-DOS batches, so the hope is this makes it
easier to extend and maintain the AppVeyor build logic. POSIX/bash isn't
supported inline by AppVeyor on Windows build machines, but we are okay
to keep it in an external script, so it's also an option.
2. CI improvements:
- enable tests for a "unity" build job.
- speed-up CI initialization by using shallow clones of the curl repo.
- speed-up CMake MSVC jobs with `TrackFileAccess=false`.
- enable parallelism in `VisualStudioSolution` builds.
- display CMake version before builds.
- always show the CPU in job names.
- tell which jobs are build-only in job names.
- move `TESTING:` value next to `DISABLED_TESTS:` in two jobs.
- add `config.log` (autotools) to dumped logs (need to enable manually).
3. Style:
- use single-quotes in YAML like we do in other CI YAML files.
It also allows to drop quoting characters and lighter to write/read.
(keep double quotes for PowerShell strings needing expansion.)

tool: use our own stderr variable
Earlier this year we changed our own stderr variable to use the standard
name `stderr` (to avoid bugs where someone is using `stderr` instead of
the curl-tool specific variable). This solution needed to override the
standard `stderr` symbol via the preprocessor. This in turn didn't play
well with unity builds and caused curl tool to crash or stay silent due
to an uninitialized stderr. This was a hard to find issue, fixed by
manually breaking out one file from the unity sources.
To avoid two these two tricks, this patch implements a different
solution: Restore using our own local variable for our stderr output and
leave `stderr` as-is. To avoid using `stderr` by mistake, add a
`checksrc` rule (based on logic we already used in lib for `strerror`)
that detects any `stderr` use in `src` and points to using our own
variable instead: `tool_stderr`.

multi: round the timeout up to prevent early wakeups
Curl_timediff rounds down to the millisecond, so curl_multi_perform can
be called too early, then we get a timeout of 0 and call it again.
The code already handled the case of timeouts which expired less than
1ms in the future. By rounding up, we make sure we will never ask the
platform to wake up too early.
Suspicious implicit sign extension: "src[i]" with type "unsigned char
const" (8 bits, unsigned) is promoted in "src[i] << (1 - i % 2 << 3)" to
type "int" (32 bits, signed), then sign-extended to type "unsigned long"
(64 bits, unsigned). If "src[i] << (1 - i % 2 << 3)" is greater than
0x7FFFFFFF, the upper bits of the result will all be 1.
The value will not be greater than 0x7FFFFFFF so this still cannot
happen.
Also, switch to ints here instead of longs. The values stored are 16 bit
so at least no need to use 64 bit variables. Also, longs are 32 bit on
