Initial system feature codegen prototype
Add a simple codegen utility for system features that:
* Exports a `hasFeatureX` method for each defined system feature
* Hardcodes the result if readonly system features are enabled
* Falls back to a runtime query otherwise
Note that this tool is not yet used, referenced, or enabled in any
production code. Follow-up changes will route build flags into
inputs for the codegen, and the outputs will be wired into the
framework.
Test: atest systemfeatures-gen-tests --host
