Add Arm64EC support (microsoft#338)
This change adds Arm64EC detours support. It bumps the toolset version to 143 from 142 since 142 does not support Arm64EC officially. It adds a new Arm64EC target. It passes Arm64EC-specific compilation flag /arm64EC and linker flag /machine:arm64x or /machine:arm64ec in right places.
