RDART-930: Refactor handles (#1550)

* Refactor handles subscription.dart

* Refactor: use import over part for handle_base.dart

* Fix regression: Check if close on handle deref

* TMP: Skip some tests (something broke with RootedHandle)

* Ups!

* Wip

* After rebase

* wip

* Fix after rebase

* Revert "TMP: Skip some tests (something broke with RootedHandle)"

This reverts commit 5081217.

* Fix nullPtr related bug

* Doh! I'll go die in shame!!

* Refactor RealmHandle

* Refactor ConfigHandle

* Refactor _RealmQueryHandler (now QueryHandle)

* Refactor RealmObjectHandle (now ObjectHandle)

* Refactor RealmResultHandle (now ResultsHandle)

* More RealmHandle stuff

* Don't need Tuple

* Expose disableAutoRefreshForTesting

* Refactor UserHandle

* RealmHandle.findAll

* Realm.find/.findExiting/.renameProperty

* Drop superfluous this.

* Refactor AppHandle

* Refactor SchedulerHandle

* Move config handles

* Refactor RealmListHandle (now ListHandle)

* Refactor RealmSetHandle (now SetHandle)

* Refactor RealmAppCredentialsHandle (now CredentialsHandle)

* WIP

* WIP2

* Organize imports

* ResultsHandle stuff

* More UserHandle stuff

* subscribeForSchemaNotification (something rubs me the wrong way about this)

* Move MapHandle.query

* More ObjectHandle stuff

* Move callback functions into handle files

* Move XTokenHandles

* toNative extension method replaces toRealmValue function

* Replace last use of deprecated Pointer.elementAt(i)

* More RealmHandle stuff

* Replace invokeGetBool and invokeGetPointer

* Run melos custom_format

   * Fixed a `DecryptionFailed` exception thrown when opening a small (<4k of data) Realm generated on a device with a page size of 4k if it was bundled and opened on a device with a larger page size.
   * Fixed an issue during a subsequent open of an encrypted Realm for some rare allocation patterns when the top ref was within ~50 bytes of the end of a page. This could manifest as a DecryptionFailed exception or as an assertion: `encrypted_file_mapping.hpp:183: Assertion failed: local_ndx < m_page_state.size()`.
 * Schema initialization could hit an assertion failure if the sync client applied a downloaded changeset while the Realm file was in the process of being opened. (Core 14.6.0)
-* Improve perfomance of "chained OR equality" queries for UUID/ObjectId types and RQL parsed "IN" queries on string/int/uuid/objectid types. (Core 14.6.0)
+* Improve performance of "chained OR equality" queries for UUID/ObjectId types and RQL parsed "IN" queries on string/int/uuid/objectid types. (Core 14.6.0)
 * Fixed a bug when running a IN query (or a query of the pattern `x == 1 OR x == 2 OR x == 3`) when evaluating on a string property with an empty string in the search condition. Matches with an empty string would have been evaluated as if searching for a null string instead. (Core 14.6.2)

 * Removed `SchemaObject.properties` - instead, `SchemaObject` is now an iterable collection of `Property`. (Issue [#1449](https://github.com/realm/realm-dart/issues/1449))
 * `SyncProgress.transferredBytes` and `SyncProgress.transferableBytes` have been consolidated into `SyncProgress.progressEstimate`. The values reported previously were incorrect and did not accurately represent bytes either. The new field better conveys the uncertainty around the progress being reported. With this release, we're reporting accurate estimates for upload progress, but estimating downloads is still unreliable. A future server and SDK release will add better estimations for download progress. (Issue [#1562](https://github.com/realm/realm-dart/issues/1562))
-* `Realm.logger` is no longer settable, and no longer implements `Logger` from package `logging`. In particular you can no longer call `Realm.logger.level =`. Instead you should call `Realm.logger.setLogLevel(RealmLogLevel level, {RealmLogCategory? category})` that takes an optional category. If no category is exlicitly given, then `RealmLogCategory.realm` is assumed.

-  Also, note that setting a level is no longer local to the current isolate, but shared accross all isolates. At the core level there is just one process wide logger.
