Now that arch/metag/ has been removed, drop a bunch of metag references
in various codes across the whole tree:
- VM_GROWSUP and __VM_ARCH_PECIFIC_1.
- MT_METAG_* ELF note types.
- METAG Kconfig dependencies (FRAME_POINTER) and ranges
(MAX_STACK_SIZE_MB).
- metag cases in tools (checkstack.pl, recordmcount.c, perf).

Changes in v2:
- Drop CPUHP_AP_PERF_METAG_STARTING too (Guenter).
