…Synapse Serverless SQL Pool SKUs for query only operations

Index query breaks on TDS endpoint, but we can just skip it

sys.views does not exist on TDS endpoint

No temporal, memory optimized or sequences in these engines

Rephrase of FK query due to lack of schema functions on TDS endpoint

Smoke tested against both engines with a CRM schema

fixes #29121

Looking at all these functions and their usages, may be we should cache them in private field.

_compatibilityLevel and _engineEdition are already private fields

Yeah, we could cache the function outputs (i.e. _supportsTemporalTable), though the perf impact here would probably be negligible (it's scaffolding after all).

@smitpatel @roji Any more I need to do here - or are you just busy?

@ErikEJ sorry this didn't receive any attention. I'll likely be very busy until 7.0 is released, if nobody else on the team picks this up until then I'll revisit this.

LGTM, thanks @ErikEJ! You forgot one SupportsViewsAndIndexes (does not compile), will merge after that's fixed.
