Move build context API to o.a.m.api.build.context to avoid collision with build report API

The build report API (PR #12572) is moving to o.a.m.api.build.report.
Having both APIs under o.a.m.api.build would cause a package collision.
This moves the incremental build context types one level deeper so the
top-level o.a.m.api.build package stays available for shared types
(like Severity) if needed later.

Package moves:
- o.a.m.api.build -> o.a.m.api.build.context
- o.a.m.api.build.spi -> o.a.m.api.build.context.spi
- o.a.m.internal.build.impl -> o.a.m.internal.build.context.impl
