It turns out that MatrixClient uses a `FetchHttpApi` instance with
`opts.onlyData = true`, so it was returning the json-parsed response rather
than the raw response. Change the way we call `authedRequest` so that we get
the raw body back.

Part of https://github.com/vector-im/element-web/issues/21972. Eventually I want to replace the whole of the current `Crypto` implementation with an alternative implementation, but in order to get from here to there, I'm factoring out a common interface which will be implemented by both implementations.
I'm also determined to fix the problem where the innards of the crypto implementation are exposed to applications via the `MatrixClient.crypto` property.
It's not (yet) entirely clear what shape this interface should be, so I'm going with a minimal approach and adding things as we know we need them. This means that we need to keep the old `client.crypto` property around as well as a new `client.cryptoBackend` property. Eventually `client.crypto` will go away, but that will be a breaking change in the js-sdk.

ensureOutboundSession uses and modifies the setupPromise of the
MegolmEncryption class. Some comments suggest that setupPromise will
always resolve, in other words it should never contain a promise that
will get rejected.
Other comments also seem to suggest that the return value of
ensureOutboundSession, a promise as well, may fail.
The critical error here is that the promise that gets set as
the next setupPromise, as well as the promise that ensureOutboundSession
returns, is the same promise.
It seems that the intention was for setupPromise to contain a promise
that will always resolve to either `null` or `OutboundSessionInfo`.
We can see that a couple of lines before we set setupPromise to its new
value we construct a promise that logs and discards errors using the
`Promise.catch()` method.
The `Promise.catch()` method does not mutate the promise, instead it
returns a new promise. The intention of the original author might have
been to set the next setupPromise to the promise which `Promise.catch()`
produces.
This patch modifies the updating of setupPromise in the
ensureOutboundSession so that setupPromise discards errors correctly.
Using `>>=` to represent the promise chaining operation, setupPromise is
now updated using the following logic:
setupPromise = previousSetupPromise >>= setup >>= discardErrors
Rather than waiting for the application to call `.startClient`, upload the
device keys during `initCrypto()`. Element-R is going to approach this slightly
differently (it wants to manage the decision on key uploads itself), so this
lays some groundwork by collecting the libolm-specific bits together.
To make it easier to track down where to-device messages are getting lost,
add a custom property to each one, and log its value. Synapse will also log
this property.
If the client uses a widget to join group calls, like Element Web does, then the local device could be joined to the call without GroupCall knowing. This adds a field to GroupCall that allows the client to tell GroupCall when it's using another session to join the call.
