Unified entry point for models and parameter sets

[santacodes]

Description

Modified the existing parameter_sets API and unified entry points to accommodate model entry points. This is an extension of the existing model entry points in the pybamm-cookie project. Relevant discussion.

Fixes # (issue)

Type of change

Please add a line in the relevant section of CHANGELOG.md to document the change (include PR #) - note reverse order of PR #s. If necessary, also add to the list of breaking changes.

• New feature (non-breaking change which adds functionality)
• Optimization (back-end change that speeds up the code)
• Bug fix (non-breaking change which fixes an issue)

Key checklist:

• No style issues: $ pre-commit run (or $ nox -s pre-commit) (see CONTRIBUTING.md for how to set this up to run automatically when committing locally, in just two lines of code)
• All tests pass: $ python run-tests.py --all (or $ nox -s tests)
• The documentation builds: $ python run-tests.py --doctest (or $ nox -s doctests)

You can run integration tests, unit tests, and doctests together at once, using $ python run-tests.py --quick (or $ nox -s quick).

Further checks:

• Code is commented, particularly in hard-to-understand areas
• Tests added that prove fix is effective or that feature works

Good start @santacodes, looks like this is still a WIP? Still I have commented just a tip hoping it'd make sense.

There are some conflicts that you may want to resolve and also feel free to add [WIP] prefix to your PR title while you're on it.

@santacodes Are you still working on this?

Yes I am, it has yet to be reviewed, I will update this branch and request a review again.

Resolving merge conflicts on my branch was causing a lot of problems and it was staging a lot of files that weren't modified by me during the merge for some reason, anyway it was a small change so I manually wrote a patch file and applied the patch after resetting this branch so the history is gone. This PR still needs a review to get it merged, and this PR is directly related to - pybamm-team/pybamm.org#258 so it might be good if we have a base entry points API before the GSoC timeline.

Bumping this @valentinsulzer @agriyakhetarpal @arjxn-py as I cannot request a re-review
