Remove WSL checks and platform detection (#53526)

WSL1 isn't a supported build or execution environment for dotnet/runtime.
Because of that removing the checks and platform detection for it as
that code path isn't necessary for WSL2 anymore as it contains a fully
featured kernel which behaves just a like a usual Linux distro.

Fixes https://github.com/dotnet/runtime/issues/18258
