Revert special character escaping
I attempted to escape certain special characters in impeller to avoid invalid depfiles. While this no longer causes an invalid depfile error, unfortunately we now always recompile these files as the ninja expected escaping doesn't work as expected. Some alternatives I tried:
single escape: / - rebuilds
double escape: // - invalid
triple escape: /// rebuilds
percent escape: %% invalid
To add insult to injury, the orginal depfile isn't invalid on windows, only on macOS/linux
Ultimately this was all just a workaround to test URI encoding, but we could also just test that in the framework. I think we should revert this handling here and add integration tests to the framework repo instead.
