chore: Remove outdated experimental options

[sentrivana]

Description

Removed a handful of experimental options. Most of them now have a top-level counterpart.

I left some still in:

• record_sql_queries: This should probably be removed once data collection is out out.
• trace_lifecycle: I'd remove this when we remove the top-level trace_lifecycle at a later point.
• transport options: keeping these for now
• continuous profiler start: no top-level counterpart

Experimental max_spans option not fully removed

Medium Severity

The experimental max_spans option was dropped from the Experiments type and documented as removed, but start_transaction still reads _experiments.max_spans when sizing the span recorder. Existing tests still set that experiment, so the option continues to work at runtime even though the public API no longer includes it. Unlike before_send_log, before_send_metric, ignore_spans, and before_send_span, this lookup was not updated.

This is fine; all transaction code will be removed on this branch eventually.
