feat: Add Dockercompat Mode & DevContainer Support

[chews93319]

Issue #, if available: #387, #745

Description of changes: This PR will introduce parsing changes to support docker compatibility for various DevContainer invocations from VsCode. The introduction of dockercompat: true within Finch configuration will specifically activate certain Finch behavior to map Docker cli arguments to compatible nerdctl arguments.

Testing done:

• Manual testing on Apple M1 (arm64) launching devContainers via VsCode

• Unit Tests

  • Pre-existing
  • New within nerdctl_darwin_test.go

• Pre-existing E2E Tests

  • Possible flakiness related to "container/cosign_test.go" for macos-e2e-tests (13, test-e2e-vm-serial, X64, test) and windows-e2e-tests (test-e2e-container, amd64, test)

• [x] I've reviewed the guidance in CONTRIBUTING.md

With commit 999371ea, I resolved the buildx bug and confirmed that the handleCache is actually working correctly and extracting the "consistency" strings from the args.

Unfortunately, my devContainers experiment was now able to build an image, but unable to open it due to the length of identifier.

FATA[0000] invalid name "vsc-arbtest_devcontainers_features-f31e83368f02f49b07b37f8b815ef72280fdebe4e5bb5de366af337b5e70ae4a-features-62cc1": identifier "vsc-arbtest_devcontainers_features-f31e83368f02f49b07b37f8b815ef72280fdebe4e5bb5de366af337b5e70ae4a-features-62cc1" greater than maximum length (76 characters): invalid argument

The update to commit 9672022 is an incremental improvement:

• repaired the compile error for linux e2e tests
• refactored handleBuildx for use in all 3 platforms (Darwin, Windows, Native)
• refactored Docker build --load handler for use in all 3 platforms (Darwin, Windows, Native)
