1b98936328 Rename realm ThreadLocal to better convey what it's doing 
Every time I looked at this code I have to re-learn what it's doing.
Changing these variable names should help quite a bit.

506409a9c4 Fix realm backup creation failing when run from RealmAccess constructor 
At the point of construction, we are not on the update thread, but it
doesn't really matter at this point because there's no other usages.

e10ac45fd7 Remove probably redundant realmLock 
As far as I can tell all accesses are safe due to update thread
guarantees. The only weird one may be async writes during a
`BlockAllOperations`, but the `Compact` loop should handle this quite
amicably.

f6a61472c4 Fix occasional failure in realm test proceedings due to incorrect Debug.Assert 
After a `BlockAllOperations`, the restoration of the `updateRealm`
instance is not instance. It is posted to a `SynchronizationContext`.
The assertion which has been removed in this commit was assuming it
would always be an immediate operation.

To ensure this works as expected, I've tracked the initialised state via
a new `bool`.

1b4c89c418 Update realm to latest version 
Contains minor changes to async usage in line with upstream API changes.

I believe a feedback issue we were seeing with offset changes (the only
component using async write flow) may have been resolved by these
upstream changes (see [release
notes](https://github.com/realm/realm-dotnet/releases/tag/10.14.0)) but
am not investigating further just yet.

1a14ccc7ee Run EF migrations before migrating to realm 
Turns out that there are more than zero users that are upgrading from
old databases. I think we probably want to support this for now.

Tested against database in https://github.com/ppy/osu/discussions/16700
and one other I had locally, both work correctly.

Dean Herbert
81461be49f Skip beatmap imports where ruleset is not present in realm 
Closes #16651.

When a ruleset is not available, the `Find` call would return null. When
a null is passed to the constructor, `BeatmapInfo` would create an "osu"
ruleset, which tries to get stored to realm and fails on duplicate
primary key.

Probably need to add better safeties against this (or change that
constructor...) but this will fix the migration process.

Probably not serious enough to pull the build. This only affects
rulesets like karaoke which have custom beatmaps.

3aa681005b Skip importing scores which have no matching realm ruleset 
There's no real way to recover these unless we want to start importing
rulesets into realm. And that seems counter productive. This can only
happen if users don't have the dll present any more, and it was removed
far before realm was tracking rulesets (else it would have an
`Available=0` entry in realm to match).

778d2a71b4 Remove Task from the inner-most Import method in RealmArchiveModelImporter 
One of my pending work items for post-realm merge.

The lowest-level import task is no longer asynchronous, as we don't want
it to span multiple threads to allow easier interaction with realm.
Removing the `Task` spec simplifies a heap of usages.

Individual usages should decide whether they want to run the import
asynchronously, by either using an alternative override or spooling up a
thread themselves.

6f4c337a56 Fix a failed BlockAllOperations leaving update realm in unretrieved state 
If the operation timed out on..

```csharp
   throw new TimeoutException(@"Took too long to acquire lock");
```

..from an update thread, it would not restore the update context.

The next call would then fail on the assert that ensures a non-null
context in such cases.

Can add test coverage if required.

f30894840c Update terminology to realm "instance" rather than "context" 
This matches the terminology used by realm themselves, which feels
better.
