Ignore more types of source files

Summary:
Add more types of development-related files to the exclusion lists. These files aren't useful to index, and having them there can bog down Baloo.

BUG: 394002
BUG: 390932
CCBUG: 382117
FIXED-IN 5.47

Test Plan: Created a bunch of files of the newly excluded types. Baloo didn't index them.
