Update load tests to Vulkan SDK version 1.3.290. (#931)

1.3.290 is the first release of official iOS support and first with support
for Windows arm64.

Stop using binaries of SDL2, assimp and glew libraries stored in repo
because an updated SDL2 is needed for 1.3.290 and more platforms are
now supported. Dependencies for iOS, macOS and Windows are now obtained
through vcpkg. Those for Linux through the package manager as before.

Thus remove other_lib, other_include/{SDL2,assimp} and
other_include/GL/{glew,glxew,wglew}.h. Move the modified Vulkan
manifest files to tests/loadtests/appfwSDL/VulkanAppSDL.

This incidentally fixes #763.

These changes plus removal of the hacks for finding the iOS components
in older Vulkan SDKs means a major revamp of the load tests-related
CMake files.

vcpkg is used in manifest mode so installation of dependencies is
automatic once vcpkg is installted. This use of vcpkg led to a reshuffle
of the root CMakeLists.txt to put some options before the project()
comment so their values can be used to set VCPKG-related variables.

Deployment target for iOS is bumped to 12.0 and for macOS to 11.0 to
match what is supported by this Vulkan SDK.

The PR also fixes some unrelated problems:

1. A syntax error in scripts/mkversion most likely introduced by PR
    #922. It is unclear why CI did not fail with this.
2. Use of a query in `scripts/build_win.ps1 that returned process
    architecture not machine architecture. VS2022 Developer PowerShells
    are x86 processes leading to failure with the old query. Use
    Get-ComputerInfo instead.
3. Also in `scripts/build_win.ps1`, a warning when `PYTHON` is defined
    on the CMake configure command line if FEATURE_PYTHON is not ON.
