valve-games: Trim traces with gltrim to reduce size and runtime

The traces that were already in the repository were converted to
snappy, then trimmed to their last frame Nrespectively, and
repacked back to brotli with quality 11.

CS, CS-source, and Portal2, didn't require any specific handling and
were trimmed by running

   apitrace gltrim -f N -o $f-v2.trace $f.trace

For Half Life 2 additional setup frames were needed and the
trim command command was

   apitrace gltrim -s 243-476 -f490 $f-v2.trace $f.trace

The resulting traces all consist of a setup frame an the final
frame from the original trace.
