[vcpkg] Fix iOS toolchain detection when using the iOS community triplets (#12361)
* [vcpkg ios] Fix detection of iOS toolchain (#6003)

Added mapping of CMAKE_SYSTEM_NAME == iOS to the bundled iOS toolchain
file.

This fixes the "Unable to determine toolchain to use for
triplet arm64-ios with CMAKE_SYSTEM_NAME iOS" error.

* [vcpkg ios] Set the CMake system processor for the simulator arches (#6003)

So it's consistent for all architectures.
