Normalize SDK name in metrics to reduce cardinality of DD tags

[lobsterkatie]

In #59379, we added sdk as a tag on our event_manager metrics. As a result, the cardinality of tag combinations in DD spiked and we had to revert the change. We need to find a way to keep sending that information, but in a way that doesn't overwhelm our tag count.

For reference, the full list of values we saw in DD in the short window the change was deployed is included below.

Thoughts:

(Crossed-out items handled by #59504. The rest have been pulled into #59742.)

• This is a free-form field, so we'd probably do well to have an other category, into which we can lump stuff we don't actually care to differentiate. DONE
• There are a lot of SDKs which appear both as sentry-xxx and sentry.xxx (and some also as just the xxx part), which we can combine. DONE
• There are a bunch of raven SDKs in the list. Should we combine them with their unified-SDK versions? Or should we just lump them all together since they're all deprecated (and have been for years)? DONE, lumped in with other
• There are definitely a bunch of community SDKs in the list. How much do we care about differentiating them? DONE, lumped in with other
• There are some descriptive ones, like __filtered and __sensitive, which can be combined and/or lumped in with other. DONE, lumped in with other
• Do we care about differentiating SDKs which fall into the platform: other bucket? Which SDKs are those?
• For tag values we end up lumping into other, should we log to GCP, just we we can get a sense of what they are?
• Should we make any effort to make sure the sdk value makes sense with the platform value?

UPDATE:

In order to quickly unblock adding the data to metrics, we went with a quick-and-dirty solution (the aforementioned #59504) which:

• Considers anything not following the unified SDK naming pattern of sentry.platform.framework to be other. This includes all of the raven SDKs.
• Considers anything third-party to be other
• Only splits the JS SDKs out by actual SDK (using the full sdk value), cutting the other SDKs down to sentry.platform

In that solution, because the current use case of this data is to track merge/unmerge behavior (which differs more by platform than framework), for wrapper SDKs which emit more than one sdk value, we chose to lump values by platform rather than by SDK. (So, for example, sentry.native.android.flutter gets subsumed by sentry.native and sentry.java.android.flutter gets subsumed by sentry.java rather than being grouped together under a single flutter umbrella.) This isn't the right choice for all metrics, though, so we might want to revisit that choice in the future, especially since ideally that information should be already being gathered by the platform value (though that value in and of itself has issues; see #59075).
