fix(openai): Handle content capture with span_and_event mode

The is_content_enabled() function only recognized 'true' as a valid
value for OTEL_INSTRUMENTATION_GENAI_CAPTURE_MESSAGE_CONTENT, causing
newer enum values like 'span_and_event' to be treated as disabled.

Updated is_content_enabled() to recognize all valid ContentCapturingMode
enum values (span_only, event_only, span_and_event) in addition to the
legacy 'true' value.

Fixes #4038
