Fixes https://github.com/matrix-org/dendrite/issues/3273
As we otherwise send down device list updates which are merely useful
for the user and causes tests to be flakey:
```
❌ TestPushSync/Adding_a_push_rule_wakes_up_an_incremental_/sync (10ms)
push_test.go:57: no pushrules found in sync response: {"next_batch":"s0_0_0_0_0_1_1_0_1","device_lists":{"changed":["@user-1:hs1"]}}
```
What this does: If a `PerformDeviceCreation` request is coming from
registering an account, it does **not** send device list updates, as
they are merely useful (no joined rooms, no one to inform) . In all
other cases, the behavior is unchanged and device list updates are sent
as usual.
The `user_id` query param only has defined behavior when authenticating
with an `as_token`. For any other tokens, the presence of the parameter
should simply be ignored.

Also slightly refactors the functions and methods to rely less on the
req/res pattern we had for polylith.
Returns `M_WRONG_ROOM_KEYS_VERSION` for some endpoints as per the spec
This removes `PerformError`, which was needed when we still had
polylith.
This removes quite a bunch of
```go
if err != nil {
return err
}
if err := res.Error; err != nil {
return err.JSONResponse()
}
```
Hopefully can be read commit by commit. [skip ci]
This adds tests for `/profile`.
Also, as a first change in this regard, refactors the methods defined on
the `UserInternalAPI` to not use structs as the request/response
parameters.
