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 Co-authored-by: Mitchell Syer <syer10@users.noreply.github.com> * Refactor: stick to `Path` instead of `File` Also extracts the downloading of CEF to a separate method * Lint * Support disabling CEF Co-authored-by: Kolby Moroz Liebl <31669092+kolbyml@users.noreply.github.com> * 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 Co-authored-by: Mitchell Syer <Syer10@users.noreply.github.com> * 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 --------- Co-authored-by: Mitchell Syer <syer10@users.noreply.github.com> Co-authored-by: Kolby Moroz Liebl <31669092+kolbyml@users.noreply.github.com>
