soc/intel/meteorlake: Rename shared SRAM aliases

Rename shared SRAM aliases for IOE and PMC to make them more readable.

pci device 13.3 is IOE shared sram, renamed to ioe_shared_sram.
pci device 14.2 is PMC shared sram, renamed to pmc_shared_sram.

Rename them in SOC code as well as mainboard to make sure the patch
builds for the relevant boards.

BUG=b:262501347
TEST=Able to build.
