Replace the inhouse collection dependency resolver with resolvelib
PR #72591

This change:

  * Adds an artifacts manager that abstracts away extracting the
    metadata from artifacts, downloading and caching them in a
    temporary location.

  * Adds `resolvelib` to direct ansible-core dependencies[0].

  * Implements a `resolvelib`-based dependency resolver for
    `collection` subcommands that replaces the legacy
    in-house code.

    This is a dependency resolution library that pip 20.3+ uses
    by default. It's now integrated for use for the collection
    dependency resolution in ansible-galaxy CLI.

  * Refactors of the `ansible-galaxy collection` CLI.
    In particular, it:

      - reimplements most of the `download`, `install`, `list` and
        `verify` subcommands from scratch;

      - reuses helper bits previously moved out into external modules;

      - replaces the old in-house resolver with a more clear
        implementation based on the resolvelib library[0][1][2].

  * Adds a multi Galaxy API proxy layer that abstracts accessing the
    version and dependencies via API or local artifacts manager.

  * Makes `GalaxyAPI` instances sortable.

  * Adds string representation methods to `GalaxyAPI`.

  * Adds dev representation to `GalaxyAPI`.

  * Removes unnecessary integration and unit tests.

  * Aligns the tests with the new expectations.

  * Adds more tests, integration ones in particular.
