Move availability inline (grpc#68)

glbrntt · web-flow · commit f0f110af87a8 · 2025-05-16T12:11:25.000+01:00
Motivation:

It's hard for packages to incrementally adopt gRPC with platforms in the
package manifest as it requires packages to include platforms in their
manifest or mint a new major version.

Modifications:

- Move platform availability onto source code
- Check annotations in CI

Result:

Easier to adopt
