BaseTools: add CLANG35 toolchain with AARCH64 support

This adds support for building the AARCH64 platforms using the
Clang compiler and assembler combined with the GNU (cross-)linker.

The chosen name CLANG35 is based on version 3.5 being the oldest
supported version, but no issues are known that should prevent its
use with any later version.
