This adds a layer of indirection around descriptor ID generation in order to facilitate injecting transactional generation. Release note: None
This commit adds a testing knob which results in descriptor ID generation being handled transactionally. The logictests now use this knob. Fixes cockroachdb#37751 Fixes cockroachdb#69226 Release note: None

I'm pretty certain that this change is not causing any of the failures. They seem to be under stressrace. This change forces lots of those to run, and they seem flakey. This change doesn't affect any of those tests, so I don't think it's related. TFTR! bors r+ |

In cockroachdb#85366, we introduced a mechanism to make descriptor ID generation transactional and, in the absence of parallelism, deterministic. That PR failed to set the knob for secondary tenant configurations. This commit rectifies that oversight. This should allow us to avoid flakes like: https://teamcity.cockroachdb.com/buildConfiguration/Cockroach_GitHubCiOptional/5939930?showRootCauses=false&expandBuildChangesSection=true&expandBuildProblemsSection=true&expandBuildTestsSection=true Release note: None

The first commit adds an interface for descriptor ID generation and propagates the interface from the ExecCfg into the EvalContext. There are some minor refactoring to avoid propagating an ExecCfg further up the stack by making the parameters more specific. The second commit adds a testing knob to use a transactional implementation in the EvalContext.
Fixes #37751
