py/emitglue: Always flush caches when assigning native ARM code.
Prior to this commit, cache flushing for ARM native code was done only in
the assembler code asm_thumb_end_pass()/asm_arm_end_pass(), at the last
pass of the assembler. But this misses flushing the cache when loading
native code from an .mpy file, ie in persistentcode.c.
The change here makes sure the cache is always flushed/cleaned/invalidated
when assigning native code on ARM architectures.
This problem was found running tests/micropython/import_mpy_native_gc.py on
the mimxrt port.
