[bug] MSBuildToolchain doesn't honor compiler.runtime_type

[SpaceIm]

Describe the bug

MSBuildToolchain doesn't seem to honor compiler.runtime_type from profile, and instead completely relies on build_type to determine RuntimeLibrary to inject in props file.

So for example if someone has a profile like this:

[settings]
arch=x86_64
build_type=Debug
compiler=msvc
compiler.version=193
compiler.cppstd=20
compiler.runtime=static
compiler.runtime_type=Release
os=Windows

props file will contain <RuntimeLibrary>MultiThreadedDebug</RuntimeLibrary>, while conan user would expect <RuntimeLibrary>MultiThreaded</RuntimeLibrary>.

CMakeToolchain for exemple behaves as expected, so it leads to inconsistency across different packages built with this profile.

How to reproduce it

Issue has been described in conan-io/conan-center-index#25433 with all details.
