OvfmPkg/XenHypercallLib: add missing GCC_ASM_EXPORT to XenHypercall2
GCC_ASM_EXPORT() not only exports a symbol as a function, it also emits
a .type <xxx>, %function directive, which is used by the ARM linker to
decide whether to emit interworking branches. So replace the explicit
.global with GCC_ASM_EXPORT(), or the code will not be callable from
Thumb-2 code.
