Make crate apex_available:{platform,anyapex}main-16k

Add the apex_available entry which cargo2android.py would add nowadays,
to make it available to address the following error:

    error: <FILE>: module "<APEX>" variant "<VAR>": "<LIB>" requires
    "libmanaged" that doesn't list the APEX under 'apex_available'.
