cpu/x86/mtrr: Make useful MTRR functions available for all boot stages
This patch migrates a few useful MTRR functions as below from
`earlymtrr.c` file to newly created common stage file `mtrrlib.c`.
1. get_free_var_mtrr
2. set_var_mtrr
3. clear_all_var_mtrr
These functions can be used to perform the MTRR programming from IA
common code SPI driver as `fast_spi.c` without requiring two separate
implementations for early boot stage (till romstage) and for ramstage
onwards.
BUG=b:225766934
TEST=Able to build and boot google/redrix board to ChromeOS.
