[mdatagen] add unsupported_platforms support and enable several components (open-telemetry#30640)

**Description:**
Add `supported_platforms` to enable components to describe which
platforms are supported, meanwhile this configuration can also be used
to generate the liftcycle test to skip windows when the component does
not support windows.

**Link to tracking Issue:** fix open-telemetry#30561
