This adds very basic cache (literally just a `Map` for now) to store room alias to room ID mappings. The improves the perceived performance of Riot when switching rooms via browser navigation (back / forward), as we no longer try to resolve the room alias every time. The cache is only in memory, so reloading manually or as part of the clear cache process will start afresh. Fixes https://github.com/vector-im/riot-web/issues/10020

/**

* This is meant to be a cache of room alias to room ID so that moving between
|
|
* rooms happens smoothly (for example using browser back / forward buttons).
|
|
*
|
|
* For the moment, it's in memory only and so only applies for the current
|
|
* session for simplicity, but could be extended further in the future.
|
|
*
|
|
* A similar thing could also be achieved via `pushState` with a state object,
|
|
* but keeping it separate like this seems easier in case we do want to extend.
