Adopted lowercase => internal pattern for LFS3_tag_* tags

Browse Source 
This includes the mask/rm/grow bits:

- LFS3_tag_RM
- LFS3_tag_GROW
- LFS3_tag_MASK0/2/8/12

Our in-device only handle types:

- LFS3_tag_ORPHAN
- LFS3_tag_TRV
- LFS3_tag_UNKNOWN

And in-device only tags with special behavior:

- LFS3_tag_INTERNAL
- LFS3_tag_RATTRS
- LFS3_tag_SHRUBCOMMIT
- LFS3_tag_GRMPUSH
- LFS3_tag_MOVE
- LFS3_tag_ATTRS

Usually I'm not a big fan of case-sensitive naming patterns, but this
has been useful for self-documenting what compat flags are in-device
only. Might as well extend the idea to our tag definitions.
