Before this PR users would need to download unused dependencies to just extract the wheels. The minimum list of deps are - packaging and installer for our whl_installer tool to properly work. This also means that we could not dogfood our whl_installer tool in the pip-tools implementation.

With this PR we start using whl_archive which just patches, extracts the wheel and parses METADATA where possible and this is the first step towards separating how sdists are treated.

Summary:

• refactor: split out whl_archive_impl function for just whls
• refactor: make the implementation of the 'whl_archive' more minimal
• use whl_archive in internal deps
• use a py_library in pip_compile rule.
• remove unused attrs from 'whl_archive'
