py/persistentcode: Decouple native code loading from emitters' presence.

Browse Source 
This commit lets the interpreter load MPY files containing native code
even if the target platform does not have a native emitter, or if native
code generation is disabled.

Native code loading has been tied to native code generation being
enabled as a discriminant to allow said operation.  This blocks native
code loading on platforms that could benefit from such a thing but they
don't (and probably won't) have a native code generation target written
for them (ie. AArch64 and RISC-V 64).  This also forces a firmware image
to have a full native code compiler present even if it doesn't need to
generate anything, as native modules already have all the code they will
ever need to load.

There is a new configuration setting,
MICROPY_PERSISTENT_CODE_LOAD_NATIVE, that if enabled it will allow
loading native code modules even if code generation
(MICROPY_EMIT_<platform> and MICROPY_EMIT_INLINE_<platform>) is
explicitly turned off.
