[tint] Auto-generate a benchmark input header
The Chrome Perf waterfall prefers test binaries to be standalone with
no runtime dependencies. This script collects all WGSL and SPIR-V
shaders in `test/tint/benchmark/` and converts them to string literals
and constant arrays in a single header file that can be included by
the benchmark binary. It also defines the macro that registers each of
these shaders with Google Benchmark.
