feat(gta-streaming-five): add face overlays data mounter

[DaniGP17]

Goal of this PR

Add a file builder for CPedFacialOverlays as suggested in this forum post: https://forum.cfx.re/t/addon-make-up-lipstick-brows-beards-etc/5224039

This allows you to add blemishes, facial hair, eyebrow, makeup, aging, etc. addons without replacing an existing one.

The default file used is update/update.rpf/common/data/effects/peds/facial_overlays.meta. You can use this as a base to create new facial overlays. Here is a test script to demonstrate a makeup addon.
FacialOverlay.zip

The code for this pull request was created by Disquse. I simply checked that it works and created a test script, but all the work is theirs. If for any reason they want me to delete this PR, I have no problem doing so.

How is this PR achieving the goal

Declaring the LoadFromStructure function to parse the .meta file and read its data. A custom file mounter has been created, and the LoadDataFile and UnloadDataFile functions insert it into the game's overlay store.
