[Tooling, Code Health] refactor: split Makefile into multiple files

[bryanchriswhite]

Summary

The Makefile has gotten quite large (1185 LoC). This PR splits the makefile into multiple files, focusing on large groups of targets and groups related to on-chain state or local/devnets:

• warnings.mk
• todos.mk
• checks.mk
• tests.mk
• localnet.mk
• testnet.mk
• params.mk
• applications.mk
• suppliers.mk
• gateways.mk
• session.mk
• claims.mk

Issue

• Reaction to friction experienced while working on #799

Type of change

Select one or more from the following:

• [ ] New feature, functionality or library

• [ ] Bug fix
• [x] Code health or cleanup
• [ ] Documentation
• [ ] Other (specify)

Testing

• [ ] Documentation: make docusaurus_start; only needed if you make doc changes
• [x] Unit Tests: make go_develop_and_test
• [ ] LocalNet E2E Tests: make test_e2e
• [ ] DevNet E2E Tests: Add the devnet-test-e2e label to the PR.

Sanity Checklist

• [x] I have tested my changes using the available tooling
• [x] I have commented my code
• [x] I have performed a self-review of my own code; both comments & source code
• [ ] I create and reference any new tickets, if applicable
• [ ] I have left TODOs throughout the codebase, if applicable

The CI will now also run the e2e tests on devnet, which increases the time it takes to complete all CI checks.

You may need to run make trigger_ci to submit an empty commit that'll trigger the tests.
