Update CMAKE_VS_PLATFORM_TOOLSET matching rules for Intel compilers.
The logic added by !5579 (merged) matches a specific toolset known to be the icx.exe compiler, and
assumes all other Intel C++ compilers (that are not DPC++) must be
icl.exe.
Since icx.exe is officially replacing icl.exe, use a regex that
matches the now-fixed set of toolsets known to use icl.exe. Any other
Intel C++ compiler will be assumed to be icx.exe.
