arm64: mte: Fix the stack frame size warning in mte_dump_tag_range()
With 64K page configurations, the tags array stored on the stack of the
mte_dump_tag_range() function is 2048 bytes, triggering a compiler
warning when CONFIG_FRAME_WARN is enabled. Switch to a kmalloc()
allocation via mte_allocate_tag_storage().
