Source filters, move search to SourceMangas

[Robonau]

implementation of the /api/v1/source/{sourceId}/filters endpoint

right side (mangadex, different per source):

groups appear on top of the filters:

something JUI already implemented

should i combine search in to browse
or should i move filtering over to search?
(personally i thing combining search in to browse makes more sense)
i currently have filter coded for the browse page (/popular), but filtering on the /search endpoint

[Robonau]

rather than using resetFilterValue and updateFilterValue i should probably use a useState
and pass through the set

spamming too many options in quick succession will break it, i should be able to fix if i move to useStates

your commit naming is fun

[Robonau]

i never know what to actually call my commits, so they tend to get pretty random

worked out the breaking that was happening in the last commit.
im probably using useState for more than is necessary, only really needed to do triggerUpdate and Data.
but im done for now, imma open for review.

search is always right under the reset button

Here are a brief changes list from visual testing

• the looks need a change to become inline with rest of the design(steal design from Tachiyomi)
• move search to Appbar
• convert the filter button to a FAB (copying Tachiyomi, not sure which design is better?)
• don't perfom search at filter input changes, have a Apply/Submit button to reduce network calls, optimize filter update network calls
• when filter results are loading, MangaGrid shows "No Manga Was found", instead it should show a loading spinner

I'll do a code review when at least non-design issues are fixed.
