Stabilize Logs Enabled

[pellared]

Stabilize Logger.Enabled API and how SDK implements it.

Blockers:

• Define Enabled parameters for Logger #4203
• Specify how Logs SDK implements Enabled #4207
• Do not require extensible Logger.Enabled parameters list  #4221
• Add EventName parameter to Logger.Enabled #4220

Question to @open-telemetry/technical-committee: Do we want to stabilize the Logger.Enabled API sooner than we stabilize the spec defining how SDK implements it? Or do we want to stabilize Enabled for API and SDK at the same time?
