Closes #54193

Additionally, respects `cacheFrom` and `options` args defined in
devcontainer.json's `build` object. Also, addresses a bug which was
hiding these problems by overriding the primary build target with
aliasing.

Release Notes:

- Fixed an image aliasing but, respect build context and build args in
dev containers
