UnitTestFrameworkPkg: FunctionMockLib: Do not support AArch64

Current FunctionMockLib is relying on the subhoob module to support the
backend operation by bitbanging the binary post-disassembly.

However subhook module is a x64 centric module and does not support
AArch64 usage.

This change removes the mock function support for AArch64. The
functionality will need other solutions to be properly supported.
