Adds support to index files for embedded mode

TODO:

• support local files
• better guess for adapter from filenames
  currently using similar logic to guess adapter from add assembly
• refactor index driver

Note: this will most likely delay the release of text-searching
Other discussiona found here Update trix to return the matched search term if it is not part of the label

maybe we push back release day to tomorrow or something? or we can release without this pr, probably ok too

@cmdcolin I am ok with releasing without this PR. However, this PR introduces a small change to the meta.json. Do we want to wait to get the label enhancements merged?

[cmdcolin]

#2289 (label enhancement) likely won't be done yet. I'm not confident in the trix-js code underlying it yet so it is draft and we could release without it

[teresam856]

Ok, I think we can go ahead with the release then.

Closing, this is getting addressed in #2303
