156691: sql: fix a couple of spots where we missed JSONPATH and LTREE r=yuzefovich a=yuzefovich

We forgot to include `DJsonpath` and `DLTree` into some of the type switches when converting datums into string format for miscellaneous builtins. This is now fixed. I decided to omit a release note given these seem like edge cases.

156954: roachtest/npgsql: skip on s390x r=fqazi a=fqazi

Previously, the npgsql test was running on S390X, which doesn't have the required binaries. To address this, this patch excludes the IBM cloud.

Fixes: #156622

Release note: None

155564: *: remove remaining references of the meta issue for secondary test tenants r=yuzefovich a=yuzefovich

**logictest: reference separate issue for disabling test tenant**

**base: remove TODOTestTenantDisabled**

All test tenant skips now have specific issues.

***: remove remaining references of the meta issue**

Going forward, #76378 will be the meta issue tracking all remaining work
for investigating and enabling test tenants across our tests. This
commit removes the last explicit mentions of the issue by replacing with
specific ones or enabling test tenants on some packages that happened to
just work.
