ref: Remove old OTel support code (#6935)

- Remove everything in `integrations/opentelemetry`
(`SentrySpanProcessor`, `SentryPropagator`, etc.)
- Remove associated test files and CI config
- Move old propagator functions and consts that we were using in
`OTLPIntegration` to the OTLP propagator directly
- Remove `instrumenter`

Note: `NoOpSpan` was not removed because it makes mypy blow up. Not
worth the effort as we'll anyway get rid of it when dropping transaction
based tracing.

#### Issues
Closes #6932

 - Transaction profiling and related code was removed.
 - Removed the deprecated Hub class and all uses of hub throughout the SDK in arguments, options, etc. Use a scope instead.
+- The `SentrySpanProcessor`, `SentryPropagator`, `instrumenter`, and associated OpenTelemetry compatibility code was removed along with the `opentelemetry` extra and the `SentryPropagator` entrypoint. Use the `OTLPIntegration` instead.
 - Removed the `auto_session_tracing` decorator. Use `track_session` instead.
 - The experimental option `otel_powered_performance` has been removed together with the associated `OpenTelemetryIntegration` and `opentelemetry-experimental` extra.
