vecindex: enable vector indexing by default

While vector indexing was in tech preview, it was disabled by default.
Now that we are transitioning this feature to general availability, it
needs to be enabled by default.

Epic: CRDB-52151
Release note (sql change): Vector indexing is now enabled by default.
