This commit does the following to get tests passing for
MSVC/AArch64:
* Implements spin_delay() with an ISB instruction (like we do for
gcc/clang on AArch64).
* Sets USE_ARMV8_CRC32C unconditionally. Vendor-supported versions
of Windows for AArch64 require at least ARMv8.1, which is where CRC
extension support became mandatory.
* Implements S_UNLOCK() with _InterlockedExchange(). The existing
implementation for MSVC uses _ReadWriteBarrier() (a compiler
barrier), which is insufficient for this purpose on non-TSO
architectures.
There are likely other changes required to take full advantage of
the hardware (e.g., atomics/arch-arm.h, simd.h,
pg_popcount_aarch64.c), but those can be dealt with later.

Small improvement not worth the code churn.

Eliminate warnings of Perl Critic from src/tools.
Backpatch-through: master

This is a continuation of 0c1aca461481, with some cleanup in:
- msvc_gendef.pl
- pgindent
- 005_negotiate_encryption.pl, as of an oversight of d39a49c1e459 that
has removed %params in test_matrix(), making also $server_config
useless.

warnings
This checks that certain I/O-related Perl functions properly check
their return value. Some parts of the PostgreSQL code had been a bit
sloppy about that. The new perlcritic warnings are fixed here. I
didn't design any beautiful error messages, mostly just used "or die
$!", which mostly matches existing code, and also this is
developer-level code, so having the system error plus source code
reference should be ok.
Initially, we only activate this check for a subset of what the
perlcritic check would warn about. The effective list is
chmod flock open read rename seek symlink system
The initial set of functions is picked because most existing code
already checked the return value of those, so any omissions are
probably unintended, or because it seems important for test
correctness.
The actual perlcritic configuration is written as an exclude list.
That seems better so that we are clear on what we are currently not
checking. Maybe future patches want to investigate checking some of
the other functions. (In principle, we might eventually want to check
all of them, but since this is test and build support code, not
production code, there are probably some reasonable compromises to be
made.)

There are a lot of Perl scripts in the tree, mostly code generation
and TAP tests. Occasionally, these scripts produce warnings. These
are probably always mistakes on the developer side (true positives).
Typical examples are warnings from genbki.pl or related when you make
a mess in the catalog files during development, or warnings from tests
when they massage a config file that looks different on different
hosts, or mistakes during merges (e.g., duplicate subroutine
definitions), or just mistakes that weren't noticed because there is a
lot of output in a verbose build.
This changes all warnings into fatal errors, by replacing
use warnings;
by
use warnings FATAL => 'all';
in all Perl files.

This commit removes all the scripts located in src/tools/msvc/ to build
PostgreSQL with Visual Studio on Windows, meson becoming the recommended
way to achieve that. The scripts held some information that is still
relevant with meson, information kept and moved to better locations.
Comments that referred directly to the scripts are removed.
All the documentation still relevant that was in install-windows.sgml
has been moved to installation.sgml under a new subsection for Visual.
All the content specific to the scripts is removed. Some adjustments
for the documentation are planned in a follow-up set of changes.
