mm: rename ARCH_ENABLE_THP_MIGRATION to ARCH_HAS_PMD_SOFTLEAVES
CONFIG_ARCH_ENABLE_THP_MIGRATION gates PMD-level migration entries.
PMD-level device-private entries use the same migration mechanism and
therefore require the same architecture support.
Upcoming PMD-level swap entries can use the same PMD softleaf helpers
without depending on page migration, so rename the architecture gate to
CONFIG_ARCH_HAS_PMD_SOFTLEAVES. This describes the PMD entry capability
rather than one current user of it.
This is a pure rename: the set of selecting architectures (x86, arm64,
s390, riscv, loongarch, and powerpc on PPC_BOOK3S_64) and the gating
semantics are unchanged.
No functional change intended.
