vc/intel/edk2: Define FSP_SIG macro for FSP 2.x compatibility

This patch introduces the FSP_SIG macro into EDK2 headers to ensure
compilation compatibility when using FSP 2.x specifications.

Previously, the macro was only defined for FSP 1.1.

TEST=Successful build of google/rex0 with 64-bit FSP.
