Define public names of the image integration

[epenet]

Breaking change

For developers only: as the image integration now defines __all__, from homeassistant.components.image import * only imports the names listed in it, instead of every public name of the module. No such wildcard import was found in core or in the custom integrations of the HACS default repositories. Explicit imports are not affected.

Proposed change

Define the public names of the image integration with __all__, as already done by sensor, cover, select, number and other entity platforms.

This came up with @joostlek during refactoring: why the # noqa: F401 markers were needed on the package root imports, and whether they could be removed. Listing the public names in __all__ states that intent explicitly, so the markers are no longer needed.

It was checked against:

• core: every name imported from homeassistant.components.image by other integrations is included. With no_implicit_reexport temporarily enabled for the image integration (it is currently disabled for homeassistant.components.*), mypy reports no re-export issue on the 29 core modules importing from it;
• HACS: every name imported from the package root by the custom integrations in the HACS default repositories (~2,400) is included, apart from the internal DATA_COMPONENT key.

Enforcing this with mypy (no_implicit_reexport for the entity platforms) will follow once all of them define __all__. No functional change.
