[libc++][NFC] Simplify `optional::iterator` (#183230)
- Rename `__optional_iterator` into `__optional_iterator_base` and make
it part of the `__optional_{meow}_base` inheritance chain. This allows
us to get rid of a sketchy-looking downcast and shorten some code.

Pull x86 fixes from Ingo Molnar:
- Fix SEV guest boot failures in certain circumstances, due to
very early code relying on a BSS-zeroed variable that isn't
actually zeroed yet an may contain non-zero bootup values
Move the variable into the .data section go gain even earlier
zeroing
- Expose & allow the IBPB-on-Entry feature on SNP guests, which
was not properly exposed to guests due to initial implementational
caution
- Fix O= build failure when CONFIG_EFI_SBAT_FILE is using relative
file paths
- Fix the various SNC (Sub-NUMA Clustering) topology enumeration

Pull timer fix from Ingo Molnar:
"Make clock_adjtime() syscall timex validation slightly more permissive
for auxiliary clocks, to not reject syscalls based on the status field
that do not try to modify the status field.
This makes the ABI behavior in clock_adjtime() consistent with
CLOCK_REALTIME"

As a temporary hack, model the timezone change for America/Vancouver
as occurring on 2026-11-01 02:00, not on 2026-03-09. This allows
for a transition period where America/Vancouver still shows as PDT.
It also replaces "-07" with "MST" post-transition until such time
as a better abbreviation is chosen.
