cpu/x86/mtrr: Delay removing `temp` variable range MTRR snapshot

This patch delays removing `temporary` MTRR snapshots to avoid conflicts
with other operations attached with same `BS_PAYLOAD_BOOT/BS_ON_EXIT`
boot state.

BUG=b:225766934
TEST=Having variable MTRR snapshot using display_mtrrs() is able to
list only the permanent MTRRs and all temporary MTRRs are removed
prior to boot to payload.
