Instrument type temporality

[jack-berg]

Partially implements spec PR #2404.

• Add AggregationTemporality getAggregationTemporality(InstrumentType) to MetricReader / MetricExporter, replaces AggregationTemporality getPreferredTemporality().
• Does NOT add the newly specified ability for MetricReader to dictate default aggregation via Aggregation getAggregation(InstrumentType). Can add that in a followup PR, and potentially after 1.13.0.
• Changes OTEL_EXPORTER_OTLP_METRICS_TEMPORALITY to OTEL_EXPORTER_OTLP_METRICS_TEMPORALITY_PREFERENCE, with backwards compatibility until post 1.13.0
