ci(clang): add AArch64 build configuration for tftf
This patch adds build config with clang support for tftf.
Note: Currently only the compiler support is added for clang.
Assembler and the linker still defaults to GNU toolchain.
Also while compiling with clang toolchain, ARM_ARCH_MINOR flag
should be set to version 7, to cover the v8.7 architectural features.
Without it, compilation will fail for instructions.
(Eg: wfxt: wfet & wfit). Henceforth ARM_ARCH_MINOR is set to 7.
