This switches clang to be the default compiler on Windows ARM64, allowing for an override to MSVC.
Turns out MSVC builds have been broken for months, but nobody checked, so I'm just switching them off for now and setting clang as the default.
These updated scripts allow for the msbuild generator to use an external (ie, non-MSVC) clang installation properly, otherwise they failed.
They also allow for users to specify their own desired clang compiler via an environment variable.
An update to the docs will come seperately.

the static crt was selected, which isn't a problem as crt
object aren't passed between the host and the shared lib
still it's be nice to use the same runtime between both.
`SHADERC_ENABLE_SHARED_CRT` is a msvc specific option and
doesn't affect other platforms.
also switch build system from msbuild to ninja on windows.
this brings down the shaderc build time from 185 to 47 seconds
for the release libs, and 224 to 53 for the debug libs
total savings: 5 minutes!
Updates the prebuilt libs to the versions used in 4.4
Also adds a check to ensure users are using at least the version of VS2022, that was used to compile the libraries

The current usage of software-based texture operations in
the oneAPI implementation puts additional register pressure on
the GPU compiler during register allocation. And it also creates
code that requires maintenance. This commit is intended to address
this situation by utilizing a recently productized SYCL bindless
texture API to enable HW-based texture operations using
Intel GPUs' hardware sampler.
This currently translates to 1-11% rendering speedups (scene-specific)
on my Arc A770 and Arc B580. At the moment, there are small
performance regressions with NanoVDB texture operations on Arc B580
and small performance regressions in shade surface MNEE and Raytrace
kernels on Arc A770, but they look recoverable and will be handled
in the future.

Enables building of a Cubin for GPUs based on Blackwell architecture
if CUDA toolkit version 12.8 or higher is installed.
Only added sm_120 to the default set, since it is the one relevant for
consumer GPUs (RTX 5090 etc.) that are generally used with Blender.

OpenCollada used to rely on PCRE (a Perl Regexp library). Since
switching to Aras' OpenCollada fork (#122270), the library is no
longer needed, but is still required as a dependency.
This patch cleans this up by completely removing it from our build
system and linux system package installation script. This also lets
us remove it from our pre-compiled library platform repos, making the
process of recompiling our libraries from scratch easier as it wasn't
compiled by our dependency builder anymore.

This was removed to make building USD plugins easier, without the need to
compile them for Blender specifically. However it also causes errors when
using the bpy module together with the usd-core pip package.
In practice there are not many USD plugins, and often need to be compiled
for Blender specifically anyway due to the monolithic library and DCCs being
on different USD versions.
Additionally, this adds a patch to avoid conflicts when loading the
same USD library version through Blender and usd-core on Windows and macOS.
Fix#127132: Crash using bpy and usd-core pip package together.

OpenEXR: 3.3.2
OpenColorIO: 2.4.1
OpenVDB: 12.0.0
Also sync up exact FFMPEG version with reference (6.1.1, from
`versions.cmake`), and accept 7.x versions since Blender should also be
compatible with this major release.
