This adds a code generator, implemented in Go. This PR also prepares `Options.h` (the ground truth) by simplifying its syntax just a bit. The ground truth file must have very simple C++ syntax, which is described in the README: https://github.com/google/filament/blob/pr/codegen2/tools/codegen-options/README.md This process revealed a small bug: `Filter.MEDIAN` was bound to the incorrect value in Java. The generated code is not yet used, stay tuned.
