Auto merge of #29877 - mrobinson:unegg-tidy, r=jdm

Convert tidy to a non-egg Python package

It seems that servo-tidy is only used by webrender in my GitHub searches. WebRender could simply use `rustfmt` and the tidy on pypi hasn't been updated since 2018. Converting tidy to a normal Python package removes the maintenance burden of continually fixing the easy install configuration.

Fixes #29094.
Fixes #29334.
