feat(performance): Adds exclusive time and measurements to spans

[edwardgou-sentry]

Adds exclusive_time and measurements as fields to the Span class. Drops measurements from Transactions since it is now inherited from spans.

Note: this changes SpanAttributes type and allows Measurements as a value

This will be used in standalone INP spans

[AbhiPrasad]

This breaks OTEL compatibility unfortunately. We'll just add them to span data directly for now, but we need a bigger strategy afterwards.

[edwardgou-sentry]

Yeah I think we'll probably have to flatten measurements into the attributes, or something similar in the future
