x86/mp_init: Add configurable stack size for SMM relocate
A stack overrun has been observed on AMD64 CPUs during the SMM module
relocation process. Change the assumed required size from equaling the
save structure's size to a Kconfig symbol.
A value of 0x400 doubles the size used by AMD64 systems and maintains
the size used by EM64T.

TEST=S3 on Grunt and verify 0x2f000-0x30000 uncorrupted
