armltdclang: add support for ARM Ltd.'s `armclang` toolchain

This is another toolchain also called `armclang`, but it is not a cross
compiler like Keil's `armclang`. It is essentially the same as `clang`
based on its interface and CMake's support of the toolchain.

Use an `armltd` prefix for the compiler ID.

Fixes: #7255
