Niklas Haas 3a2a874994 tests/checkasm: switch to external checkasm
There are a number of benefits tied to the upstream / third-party checkasm
version, including:

- Improved long-term maintainability, code reuse with other projects, etc.

- Vastly improved overall performance / runtime for benchmarking, due
  primarily to the ability to scale the runtime of each test to that test's
  complexity.

- Much more robust statistical analysis of benchmarking results; including
  robust outlier rejection, an estimation of the histogram, and the ability
  to report the variance / stddev in addition to the (trimmed) mean.

- Interactive HTML and JSON output formats in addition to CSV/TSV.

- More readable and user-friendly output across the board, especially for
  failures and data dumps (e.g. also showing errors inside padding bytes).

- Better cross-platform support, including dynamic fallback of timer
  implementations on ARM platforms, a better RISC-V harness, and more.

There are multiple approaches to how we can solve the problem of integrating
this third party checkasm into dav1d, but I think the hybrid approach of
loading it as an external dependency, falling back to a meson wrap file,
provides the best overall compromise. This avoids the messiness of git e.g.
git submodules, while still allowing us to pin individual tags.
