ANDROID: add kabi padding for structures for the android13 release

Browse Source 
There are a lot of different structures that need to have a "frozen" abi
for the next 5+ years.  Add padding to a lot of them in order to be able
to handle any future changes that might be needed due to LTS and
security fixes that might come up.

It's a best guess, based on what has happened in the past from the
5.10.0..5.10.110 release (1 1/2 years).  Yes, past changes do not mean
that future changes will also be needed in the same area, but that is a
hint that those areas are both well maintained and looked after, and
there have been previous problems found in them.

Also the list of structures that are being required based on OEM usage
in the android/ symbol lists were consulted as that's a larger list than
what has been changed in the past.

Hopefully we caught everything we need to worry about, only time will
tell...
