fix(UI): Add LCEVC label in resolution menu (#9186)

This PR adds `isLCEVC` check to the `basicResolutionComparison` and
appends `'LCEVC'` to the label text in `getResolutionLabel_` if the
track is LCEVC. This makes it easier to tell LCEVC profiles apart and
fixes an issue we were seeing when many different Dual-Track profiles
are contained in the manifest, it might be hard to differentiate them
(e.g. base and LCEVC profile with the same 1080p resolution).
