Donn bd8ce27550 Allow Including sky130A in the OpenLane Docker Image (#846) ...

+ Add a dependency system for tools, so some tools can be built first in local installs or have other repos and commits included in docker image builds
+ Add fully working `open_pdks` image that does NOT use Conda
+ Add options to list containerized tools in `dependencies/tool.py`, with a `--no-pdks` flag to exclude open_pdks
+ Add libraries/sky130_fd_pr/latest to the full PDK build (was missing)
~ Isolated PDK building stuff into `./dependencies/pdk.mk`
~ Final merge no longer uses a tarball, just uses a good 'ol copy

---
Caveat is this will not be enabled by default or used by the CI for now. The reason is the PDK adds another 3 gigabytes to the final image and takes positively forever to build.

To use an internally built PDK, you need to export two variables:

export EXTERNAL_PDK_INSTALLATION=0
export NO_PDKS=0

Then you'd `make openlane` as normal.

To finally enable this, we'd need to rewrite make_timing to not take forever (probably in Rust/Swift/Go/whatever) and Open_PDKs would need to be updated so it gzips the liberty files. We'd also need to ensure that all tools can load .lib.gz files.
