Fix ANRs when calculating DB sizes for Sentry (#7017)

* Fix ANRs when calculating DB sizes for Sentry

Instead of using the SDK's `Client.getStoreSizes()` method, manually check the sizes using the file system.

For this, the `SessionPaths` need to be synchronously accessible from a `MatrixClient`. I removed `SessionPathsProvider` too since it's not needed anymore.
