ref: Remove old OTel support code

[sentrivana]

• 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

Unused SENTRY_TRACE_KEY after move

Low Severity

SENTRY_TRACE_KEY is defined and written in extract, but nothing in the codebase reads it anymore. The old SentrySpanProcessor was the only consumer of that context value (parent_sampled), so after removing that processor this is a dead store left over from the move.

Orphaned pytest-forked in tox

Low Severity

pytest-forked was moved onto the otlp tox env in tox.ini, but otlp tests do not use @pytest.mark.forked, and the same dependency was not added to tox.jinja. That leaves an unused CI dependency and drifts the generated file from its template source.
