games/xray-16: Fix build against math.h declaring rsqrt() in recent 16
FreeBSD's <math.h> now declares double rsqrt(double), which clashes with
the engine's own rsqrt() helper:
src/xrCore/_vector3d.h:359:8: error: exception specification in
declaration does not match previous declaration
359 | double rsqrt(double v) noexcept;
/usr/include/math.h:556:9: note: previous declaration is here
556 | double rsqrt(double);
Rename the engine helper to xr_rsqrt() in its declaration, its definition
and its four call sites so it no longer collides with the libm symbol.

csh(1): Silence -Wuse-after-free warnings from GCC 12.5
GCC 12.5 generates the following -Wuse-after-free warnings, which are
all false positives, so silence them for this vendor source. I'd like
to submit the code fixes to upstream and then do a vendor update.

contrib/gcc-12: Silence -Wmaybe-uninitialized warning
GCC 12.5 would generate the following -Wmaybe-uninitialized warning for
expmed.cc, which defines the #pragma to force this diagnostic to be a
warning, so the GCC's own bootstrap that uses -Werror could succeed.
However, this #pragma makes this warning can't be silenced by a
-Wno-maybe-uninitialized option on the command line. So just modify the
source file to ignore it.

gnu/cc80: Correct CFLAGS to fix mkdep warnings
These programs require to use a C++ compiler to compile their '.c'
sources, so they used hacks to do this, one of which is overriding
'MKDEPCC=${CXX}'. However, the CFLAGS wasn't overridden, so calling
mkdep(1) programs would give the warnings:
```
cc1plus: warning: command-line option '-std=gnu11' is valid for C/ObjC but not for C++
```
Fix it by additionally overriding CC and CFLAGS, similar to the
practice used in 'cc80/cc_tools/libcpp/Makefile'. One bonus is that we
can also remove the rule overriding.

editors/vscode: Update to 1.142.0 and attempt to add support for aarch64
Support for aarch64, both VSCode editor (client) and remote extension
host (server), are added with this commit.
While here, make the following additional changes:
- update product.json for popular extensions [1]
- respect MAKE_JOBS_NUMBER when rebuilding native node modules
- return to use minified build for remote extension host
Acknowledgments: I utilized a reference instance (ref15-aarch64)
extensively while I prepared to add support for aarch64. I would like
to thank clusteradm@ for keeping reference instances in good shape.
