Switch to JCEF (#2038)

* Switch to JCEF

This is a full implementation, but it does not yet include downloading
CEF as KCEF did

* Download CEF automatically

* Handle and propagate CEF init errors

* Lint

* Simplify jcef version extract

* CEF: Download async

* Copy StartupAsync to support handling errors

Startup failures are simply swallowed, since they are recorded in the
future, but there is no way to get that exception

* CEF: Search for release file recursively

On Mac, the file is buried a bit deeper than first level, like on Win
and Linux

* KcefWebViewProvider: Suppress deprecation

We need to send those events, even if they are deprecated

* Update readme

* Optimize imports

* Suggestion

* Refactor: stick to `Path` instead of `File`

Also extracts the downloading of CEF to a separate method

* Lint

* Support disabling CEF

* Move JBR version to build constants

Allows embedding into Manifest so docker can later extract the proper version

* Create test to verify JCEF dependency matches downloaded JBR

* Update server/src/main/kotlin/suwayomi/tachidesk/server/util/CEFManager.kt

* Apply suggestions from code review

Co-authored-by: Mitchell Syer <Syer10@users.noreply.github.com>

* Fix compile, apply Path suggestions

* Download progress

* Lint

* Fix exception on non-posix

* Delete recursively

Others can be non-empty

* Support disabling CEF at will

Not really functional, but nice

* Fix test

* Exclude masstest unless explicitly requested

* PR-CI: Run tests

* Add Changelog entry
