benchmarks: Add a basic set of benchmarks
Add google benchmark to the DEPs.
Implement a basic set of benchmarks for each of the writers and the WGSL parser.
Add build rules for CMake. GN build rules TODO.
Add a simple go tool (ported from Marl) to diff two benchmarks. Less
noisy than the one provided by google benchmark.
