Integrate syntax highlighting in egit's compare editor

[systemoperator]

Description

It would be great if there was syntax highlighting integrated in egit's compare editor (diff viewer) for various programming languages.

Eclipse recently announced a new, versatile syntax highlighting functionality for more than 60 languages with TextMate and it also works in the compare editor, which should be the way to go:

Motivation

Other diff-viewers and git UIs offer that. It makes the differences easier to read and merge.

Actually that is already done in 4.32, see https://eclipse.dev/eclipse/news/4.32/platform.php#generic_editor_in_diff

All what you need is Textmate + language pack installed in 4.32 SDK. The rest is working out of the box for all types supported by Textmate.
