levels: tweak E1M5 (#1319)

Change the sofas to resemble actual sofas instead of flesh, using COMPTILEs with texture offsets to emulate chair legs without having to make new textures.

Restore Ralphis' old E1M1 track as E1M5 - taking Matt's suggestion here into heart: https://github.com/freedoom/freedoom/pull/1292#issuecomment-1913358481_

"The Raging Sun" - although I like it - is quite bland. Ralphis' old E1M1 track is a fast-action-styled track that fits the shooting gallery aspect of E1M5.

Also addressed #996 for the crate area and simplified a bit of geometry (no visual changes, just merging sectors), as well as giving more internally consistent lighting to the basement red key area.
