vc/intel/fsp/mtl: Add x86_64 FSP V3471.91 headers

This commit introduces new header files of V3471.91 for the x86_64
architecture in the fsp2_0/meteorlake directory. FSP2.4 brings FSP
64-bits support and the soc Kconfig file has been updated to select
this new header path when FSP2.4 is in use.

BUG=b:329034258
TEST=Verified x86_32 and x86_64 builds on Meteor Lake board (Rex)
