[canvaskit] Remove getproc when creating WebGL interface
This saves about 15kb of wasm code size (4kb gzipped), 11kb
of JS code size (2kb gzipped) and about 10ms
when creating a new surface (~35ms -> 25ms in a local test).
This also gates the webgl code more strongly (off unless you
really request it), since the headers won't be available
except in an emscripten environment.
