Subject: [PATCH] feat(async): use `is_async_compatible()` to determine backend
 incompatibility and error out (#1355)

Use `getters` to early exit webdav when using `async_incompatible`
backends.

Using the type system or fixing all async compatibility issue is big and
structural work.
To avoid runtime crash for our users I suggest using this getter as a
temporary fix.

tracking issue: https://github.com/rustic-rs/rustic/issues/1181 (see for
more details)

> As far as I could tell, `webdav` feature was the only one spawning a
`runtime` in `rustic` and using it.

### Before merging this one:
- [x] rustic_core (core and backend) must be updated to a release that
includes rustic-rs/rustic_core#355.
