feat: image component for both external and internal use

[MengLinMaker]

Adding Image component for #6304:

• Create image.ts component:
  • Initial creation
• Refactor function.ts and fargate.ts to use image.ts
  • function.ts
  • fargate.ts
• Test changes against sst examples:
  • examples/aws-task
  • examples/aws-python-container - only python uses container for Lambda function
• Add docs

Although efforts has been made to preserve functionality. Some behaviors may change:

• fargate.ts image name is changed. Can be preserved via transform.

@vimtor the test in platform fails since bun lacks features from node, which are required for pulumi. I will use npm node for now. Though I believe pnpm will offer a better monorepo experience.

hey @MengLinMaker no need to upgrade vitest or write tests for this feature

i'm working on a better testing setup. for the moment you can test the components against one of the local examples as described in the README

[MengLinMaker]

AFAIK some sst examples are set to use latest version from npm. But we want to use the sst currently being changed...

Are you implying the local sst should be installed globally?

[MengLinMaker]

Ah thanks its in the root README #running-locally

Then sst diff against an empty AWS account for snapshots

[vimtor]

i usually do:

1. clone the repo
2. bun install
3. go mod tidy
4. cd platform && bun run build
5. cd examples/<example> && bun install
6. go run ../../cmd/sst dev (or deploy)

if you make changes you should run 4 and 6 again

[MengLinMaker]

Not quite ready to merge, but I'd like confirm that current changes are desired.

Refactoring fargate.ts and function.ts doesn't add anything new, just cleaner abstractions.

Adding ability to use input image directly into service.ts should be straight forward.

Link issue #6304
Could also investigate #6369 after completion
