rCOMM8d55d986b329: [keyserver] Process and store encrypted media

Summary

Part of ENG-3393

Encrypted media can no longer be processed on keyserver. Modified validateAndConvert - added a simple validation based on provided MIME type - it must be provided in order to detect if we have image or video. Then the content is passed through.

Then stored the encryption key in extras column of the uploads table.

Depends on D7166

Test Plan

Modified the uploadMultimedia call in input-state-container to pass some encryptionKey. Uploaded some media. Ensured the encryptionKey is added to the uploads table

keyserver/src/uploads/media-utils.js
33 ↗	(On Diff #24065)	It feels like this function should probably take an object instead of a list of parameters, given how many of them there are and that some of them are `boolean` (which makes it unclear what's going on at the callsite)
53–58 ↗	(On Diff #24065)	`mediaConfig` tells us what kinds of files we can accept on `native` from the user, but it doesn't tell us what kind of files we can accept in `keyserver` to distribute to peers. For example, somebody is allowed to upload a `gif`, but it gets transcoded to an `mp4` or `jpeg` (depending on whether it is an animated GIF) before being uploaded to the keyserver. Your code here makes it so we change this behavior and now accept a variety of formats that we might not be able to render on clients. Instead, can we use `serverCanHandleTypes`, like we do elsewhere in this function?

keyserver/src/uploads/media-utils.js
33 ↗	(On Diff #24065)	Agreed, will change this
53–58 ↗	(On Diff #24065)	Yeah I looked at the `serverCanHandleTypes` before and it's indeed a subset of `mediaConfig` types. But my understanding was that these are types that can be processed by keyserver, and we're skipping that processing for encrypted files. That's why I used `mediaConfig` directly. Anyway, I can change it back to use `serverCanHandleTypes` because my understanding was wrong.

Updated validateAndConvert to accept a single object argument
Used serverCanHandleTypes to validate MIME type

keyserver/src/uploads/media-utils.js
70–72 ↗	(On Diff #24109)	We could consider replacing these lines with this. PS there is a typo here (extraneous `}` character in the invariant text)
53–58 ↗	(On Diff #24065)	That's fair... in retrospect, `serverCanHandleTypes` should probably be called `clientCanHandleTypes`
