TWE Tidy-up (#4367)

# About the pull request
Tidies up the TWE RMC Presets as they were a little scattered.

- Moves all the entries in the presets to be grouped properly, no more
WEAR_HEAD appearing at the bottom of the list between the contents of
droppouches.
- Removed surgical line as it was being duplicated from the surgical
kit.
- Added MRE to the MRE carrier as it was otherwise using custom backpack
and identical contents.
- Amends skills so Breacher and Pointman are no longer able to use
smartguns.
