Nikita Sirgienko 7808cbd644 CMakeDetermineCompilerId: support Intel DPC++ compiler toolset for VS gen 
Before Intel have only one compiler icl (Intel(R) C++ compiler) and
CMakeDetermineCompilerId has considered, that all toolchains with a word
"Intel" in the toolchain name is a icl compiler. But now Intel have also other
compiler - Intel(R) DPC++ compiler, which haven't working with cmake on
Visual Studio Generator because cmake try to use icl compiler, which cmake
can't found and because of this fails the configuration. This commit fix
this problem, and both compilers start to work correctly with
Visual Studio generator.

Fixes: #21546
