Remove trailing spaces

[parkerbxyz]

Proposed Changes

1. Removes trailing spaces in build.py
2. Removes trailing spaces in descriptor files
3. Regenerates files with bash build.sh

Similar to #1987. I'm proposing this change because my editor is configured to auto-delete trailing whitespace in files on save. This was causing a lot of files I worked on in #1934 to show unrelated whitespace changes. I found the source of these trailing spaces, removed them, and regenerated the files. This fixes the problem at its source and should prevent others from running into this in the future.
