feat(examples-plugins): add example plugin benchmark-js

[BioPhoton]

This PR adds benchmark to the example plugins (and later move it into official plugins).

Note

This PR includes 2 libs for benchmark testing. At them moment I'm unsure about the results and opened tinylibs/tinybench#71.
I will also wait for a couple of runs in the CI and maybe run more tests on my local machine. In a follow up PR I want to move it under our released plugins.

This plugin should execute the already existing benchmarks and generate audits of them.

In this PR:

• moved mock folder
• add benchmark-js to examples/plugins
  • tests
  • docs
  • logic
  • add target perf
• introduce tools to run perf benchmarks more organised
• refactor utils/perf to use new tooling
• added error if --tsconfig file could not resolve + tests
