feat: support configured dependency cache directory

[mikeshultz]

What I did

Adds support for new cache_folder config var which defines where to place non-project dependencies.

Example config:

name: ape-project

compile:
  cache_folder: .cache

Depends on: ApeWorX/ape#1897

How I did it

Replaces hard references to .cache to configuration. Relies on base_dir for relative paths.

How to verify it

Run against branch from above linked PR.

Does Vyper need a similar one?

Does Vyper need a similar one?

ape-vyper doesn't leverage the dependency cache folder and the base_path change seems to work just fine.

This should be g2g after next Ape release

ETA: this PR will need to be updated with that version update as well.
