soc/intel/meteorlake: Select X86_INIT_NEED_1_SIPI Kconfig

This patch helps to save 10.200ms of booting time without any issue
seen during MP Init. All cores are out from reset and alive.

Port the Alder Lake 'commit 6526e7896727 ("soc/intel/alderlake: Select X86_INIT_NEED_1_SIPI Kconfig for RPL")' also to Meteor Lake.

Additionally, no performance degradation is observed while running
benchmarks.

BUG=b:211770003
TEST=Able to boot Google, Rex to ChromeOS with all cores enabled.

Without this patch:
30:device enumeration                     1,480,217 (28,232)

With this patch:
30:device enumeration                     1,472,466 (18,334)
