Add RECORD_AS_MUCH_AS_POSSIBLE mode to TraceOptions.
With current implementation of devtool_tracing_handler, it doesn't do
anything with invalid options and just use RECORD_UNTIL_FULL by default. So
the change to telemetry's tracing backend will not break backward
compatibility for browsers that don't support "record-as-much-as-possible" option.
However, this is a hacky way to maintain backward compatibility, and we
should fix devtool_tracing_handler so it can respond with error message on
Tracing.start if there is options parsing error.
