Switch sliding sync support to simplified sliding sync (#4400)

* Switch sliding sync support to simplified sliding sync

Experimental PR to test js-sdk with simlified sliding sync.

This does not maintain support for regulaer sliding sync.

* Remove txn_id handling, ensure we always resend when req params change

* Fix some tests

* Fix remaining tests

* Mark TODOs on tests which need to die

* Linting

* Make comments lie less

* void

* Always sent full extension request

* Fix test

* Remove usage of deprecated field

* Hopefully fix DM names

* Refactor how heroes are handled in Room

* Fix how heroes work

* Linting

* Ensure that when SSS omits heroes we don't forget we had heroes

Otherwise when the room next appears the name/avatar reset to
'Empty Room' with no avatar.

* Check the right flag when doing timeline trickling

* Also change when the backpagination token is set

* Remove list ops and server-provided sort positions

SSS doesn't have them.

* Linting

* Add Room.bumpStamp

* Update crypto wasm lib

For new functions

* Add performance logging

* Fix breaking change in crypto wasm v8

* Update crypto wasm for breaking changes

See https://github.com/matrix-org/matrix-rust-sdk-crypto-wasm/releases/tag/v8.0.0
for how this was mapped from the previous API.

* Mark all tracked users as dirty on expired SSS connections

See https://github.com/matrix-org/matrix-rust-sdk/pull/3965 for
more information. Requires `Extension.onRequest` to be `async`.

* add ts extension

* Fix typedoc ref

* Add method to interface

* Don't force membership to invite

The membership was set correctly from the stripped state anyway so
this was redundant and was breaking rooms where we'd knocked.

* Missed merge

* Type import

* Make coverage happier

* More test coverage

* Grammar & formatting

* Remove markAllTrackedUsersAsDirty from crypto API

Not sure why this was in there, seems like it just needed to be in
crypto sync callbacks, which it already was.

* Remove I from interface

* API doc

* Move Hero definition to room-summary

* make comment more specific

* Move internal details into room.ts

and make the comment a proper tsdoc comment

* Use terser arrow function syntax

* Move comment to where we do the lookup

* Clarify comment

also prettier says hi

* Add comment

Co-authored-by: Richard van der Hoff <1389908+richvdh@users.noreply.github.com>

* Add tsdoc

explaining that the summary event will be modified

* more comment

* Remove unrelated changes

* Add docs & make fields optional

* Type import

* Clarify sync versions

* Make tsdoc comment & add info on when it's used.

* Rephrase comment

Co-authored-by: Richard van der Hoff <1389908+richvdh@users.noreply.github.com>

* Prettier

* Only fetch member for hero in legacy sync mode

* Split out a separate method to set SSS room summary

Rather than trying to fudge up an object that looked enough like the
old one that we could pass it in.

* Type import

* Make link work

* Nope, linter treats it as an unused import

* Add link the other way

* Add more detail to doc

* Remove unnecessary cast

Co-authored-by: Richard van der Hoff <1389908+richvdh@users.noreply.github.com>

* Remove length > 0 check

as it wasn't really necessary and may cause heroes not to be cleared?

* Doc params

* Remove unnecessary undefined comparison

Co-authored-by: Richard van der Hoff <1389908+richvdh@users.noreply.github.com>

* Put the comparison back

as it's necessary to stop typescript complaining

* Fix comment

* Fix comment
