ArmPlatformPkg/PrePeiCore: Make vector table object BTI compatible 

The object file containing the vector table does not contain any
callable functions, so it will not be implicitly annotated as BTI
compatible on BTI builds. So add the annotation by hand, and use the
'empty' type so we get the GNU ELF note but not the actual BTI opcode.
