[PATCH] include: Update ARM64 context flag definitions to match current SDKs

CONTEXT_FLOATING_POINT should be included in CONTEXT_FULL, and
there's a new flag CONTEXT_ARM64_X18 (not available without
the arch specific prefix) that only is part of CONTEXT_ALL.
Update existing code that tries to set these flags accordingly.
