Continuous Profiling

[cleptric]

Adding support for Continuous Profiling. The 30 second limit does no longer apply.
For now, we have a simple profiles aggregator, similar to logs, which we can later make smarter to support the agent.

profiler()->start();

// your code

profiler()->stop();
profiler()->flush();

Develop Docs https://develop.sentry.dev/sdk/telemetry/profiles/sample-format-v2/

• Add missing SDK options (docs are missing, tbd profiling team)
• Toggle between the legacy and continuous profiler based on SDK options
• Add debug logs
• Add support for starting the profiler prior SDK init
• Check if we need to validate the sample count
