[AArch64][SME] Resume streaming-mode on entry to exception handlers (#156638)
This patch adds a new `TargetLowering` hook `lowerEHPadEntry()` that is
called at the start of lowering EH pads in SelectionDAG. This allows the
insertion of target-specific actions on entry to exception handlers.
This is used on AArch64 to insert SME streaming-mode switches at landing
pads. This is needed as exception handlers are always entered with
PSTATE.SM off, and the function needs to resume the streaming mode of
the function body.
