This is for https://github.com/vector-im/element-web/issues/15705https://github.com/matrix-org/matrix-react-sdk/pull/5459 was unable to track down all the instances of where the issue happens, so this commit tries to do a more complete job.
Specifically, this replaces the getRoomId() function given widgets cannot reliably be referenced by widget ID in this way, and the store has been updated to handle a more unique widget ID for the store (just in case).
Further sanity checking has also been added to ensure that we are at least returning a valid result.
This should also help https://github.com/vector-im/element-web/issues/15705 by either implicitly fixing the problem, causing chaos as described in the issue, or by forcing a crash to identify the problem more easily.
This should alleviate https://github.com/vector-im/element-web/issues/15705 from happening, though the cause is still unknown.
Requiring a room ID is safe for this because only room widgets can be pinned, and widget IDs are not globally unique which means from a logical standpoint the contract still makes sense here.

This was surprisingly easy given the number of errors I remember last time, but here it is. This also includes an over-engineered VisibilityProvider with the intention that it'll get used in the future for things like Spaces and other X as Rooms stuff.
The security key naming/practice was misguided, so let's call it what it is (a settings key) and abstract away the complexity to a new store.
Fixes https://github.com/vector-im/element-web/issues/15820 while we're here.
The "remember my selection" option wasn't working because the `missing` set still included the approved permission. Solution: remove it from `missing`.
The customisation point is to allow forks to change which widgets get which additional capabilities dependent on their own rules.
Following https://github.com/matrix-org/matrix-react-sdk/pull/5385, it is now possible for a widget to request these capabilities without being a video conference or sticker picker. This commit actually enables this support for those kinds of widgets.
This commit also fixes an issue in the URL templating where some variables might get set to 'undefined' - this appears to be a scoping issue, so StopGapWidget now stores the definition alongside the superclass.
