Peter Nguyen 015ed1a7a4 sdk/metric: Support specifying cardinality limits per instrument kinds (#7855 )

Previously, we only had `WithCardinalityLimit()`, which adds a global
cardinality limit.

This PR adds a new API on the reader `WithCardinalityLimitSelector` that
can be used to specify limits per instrument kinds.


[spec](https://github.com/open-telemetry/opentelemetry-specification/blob/49845849d2d8df07059f82033f39e96c561927cf/specification/metrics/sdk.md?plain=1#L1282)


[schema](https://github.com/open-telemetry/opentelemetry-configuration/blob/3dbebe292912f0c0c96ce5dcfefc45dfe5e20f39/snippets/CardinalityLimits_kitchen_sink.yaml#L11-L18)

closes #7786
