Sky130 Enhancements (#1240)

Browse Source 
+ Add feature to match PDK names using Python `fnmatch`, allowing wildcards in `config.json` `pdk::` statements
~ open_pdks -> `e8294524e5f67c533c5d0c3afa0bcc5b2a5fa066`
- Remove "dependencies" field from tool_metadata.yml
- Removed sky130 version from tool_metadata.yml, tracked through the open_pdks "sky130.json" file instead
- Removed CVC scripts, placed in the PDK

The value for this key would be a `dict` that is only evaluated if the PDK or SCL matches those in the key, i.e., for `pdk::sky130A` as shown above, this particular `dict` will be evaluated and its values used if and only if the PDK is set to `sky130A`, meanwhile with say, `asap7`, it will not be evaluated.
The match is evaluated using [`fnmatch`](https://docs.python.org/3.6/library/fnmatch.html), giving it limited wildcard support: meaning that `pdk::sky130*` would match both `sky130A` and `sky130B`.
Note that ***the order of declarations matter here***: as seen in the following example, despite a more specific value for a PDK existing, the unconditionally declared value later in the code would end up overwriting it:
