Fix: Build error with MSVC 2017

BKE_cryptomatte_extract_layer_name was using std::isdigit
without including <cctype> somehow only MSVC 2017 had a
problem with that.

Clean-up: Fix build warning with MSVC

Callback function was using int while update_render_passes_cb_t was
using eNodeSocketDatatype leading to a build warning about different
argument types with MSVC.

Fix: Python warning in windows debug builds

When doing a debug build on windows, blender will
start with the following warning:

"Unable to find the python binary, the multiprocessing
module may not be functional!"

The root cause for this issue is: for a debug build
the python binary is called python_d.exe rather than
just python.exe

This change fixes BKE_appdir_program_python_search
to look for the _d suffix for debug builds on windows

Fix: Fix potential memory leak in BLI_getenv

Issue introduced in rB87b19b3aba0c and unlikely to occur
but no reason not to have correct code.

Fix: BLI_getenv returns ascii not UTF8 on windows

BLI_getenv has always incorrectly returned ascii rather
than UTF-8. This change corrects this behaviour.

This resolves issues when the `BLENDER_USER_CONFIG`
environment variable contains a path with Unicode characters
on windows as reported in T74510 (but unlikely the root
cause for the issue at hand there)

MSVC: Enable clang-tidy analyser

This enables the use of clang-tidy in the VS IDE.

To use it:

1 - Enable WITH_CLANG_TIDY in your cmake configuration
2 - From the Analyse pull down menu select Run Code Analysis on...

The analyser is currently not enabled by default on build
given it is quite slow and there are quite a few problems
it reports that we still need to deal with.

Windows/Ninja: allow parameters for rebuild.cmd

The windows build leaves a convenience helper script
in the build folder called, rebuild.cmd. This change
passes any parameters you give rebuild.cmd to ninja
so you can easily pass it additional parameters without
having to edit the batch file manually.

Deps: PugiXML 1.10

This separates out PugiXML that was previously
bundled by OIIO.

As this linux/mac libs are not available
this commit only contains the builder and windows
changes, and the option to enable pugixml is
guarded by a platform if, this can be removed
once all platforms have committed the svn libs.

Windows: Fix build issue with VCPKG

For blender we disable VCPKG to prevent it from picking
up the wrong libraries from VCPKG rather than our lib folder
some of the cycles tests needed this to link correctly.
