feat(server): transcode bitrate and thread settings (#2488)

Browse Source 
* support for two-pass transcoding

* added max bitrate and thread to transcode api

* admin page setting desc+bitrate and thread options

* Update web/src/lib/components/admin-page/settings/setting-input-field.svelte

Co-authored-by: Michel Heusschen <59014050+michelheusschen@users.noreply.github.com>

* Update web/src/lib/components/admin-page/settings/setting-input-field.svelte

Co-authored-by: Michel Heusschen <59014050+michelheusschen@users.noreply.github.com>

* two-pass slider, `crf` and `threads` as numbers

* updated and added transcode tests

* refactored `getFfmpegOptions`

* default `threads`, `maxBitrate` now 0, more tests

* vp9 constant quality mode

* fixed nullable `crf` and `threads`

* fixed two-pass slider, added apiproperty

* optional `desc` for `SettingSelect`

* disable two-pass if settings are incompatible

* fixed test

* transcode interface
