RUM-5540: Add stop and start apis for session replay

[jonathanmos]

What does this PR do?

• Adds apis to manually start and stop session replay

SessionReplay.stopRecording() SessionReplay.startRecording

• Adds an option to SessionReplayConfiguration so that users can choose to not start recording automatically

SessionReplayConfiguration.. .startRecordingImmediately(false)

• webviews will not be recorded when SR is stopped
• has_replay will be sent as 'false' to the backend when SR is stopped
• startRecordingImmediately will be sent to the backend in the config telemetry

Motivation

Give users the option to stop and start recordings manually.

It would be great to get some additional Android input as well.

Hadn't seen @mariusc83's review :)
