While previously the allocator only evaluated using liveness obtained
from gossip, this change introduces a new `OverrideStorePool` struct
which can be used to override the liveness of a node for the purposes of
evaluating allocator actions and targets.  This `OverrideStorePool` is
backed by an existing actual `StorePool`, which retains the majority of
its logic.

Depends on cockroachdb#91461.

Part of cockroachdb#91570.

Release note: None

This change adds methods to be to evaluate allocator actions and targets
utilizing a passed-in `StorePool` object, allowing for the allocator to
consider potential scenarios rather than those simply based on the
current liveness.

90649: sql: support indexes in regclass cast and pg_table_is_visible r=ajwerner a=rafiss

fixes #88097

### sql: remove deprecated function from DatabaseCatalog

The ParseQualifiedTableName function was deprecated and unused.

### sql: support casts from index name to regclass

Release note (sql change): Casts from index name to regclass are now
supported. Previously, only table names could be cast to regclass.

### sql: add index on pg_namespace(oid)

This will allow us to efficiently join to this table.

### sql: fix pg_table_is_visible to handle indexes

This uses the internal executor now to do the introspection using
pg_class where everything can be looked up all at once.

There's an increase in number of round trips, but it's a constant
factor.

Release note (bug fix): Fixed the pg_table_is_visible builtin function
so it correctly reports visibility of indexes based on the current
search_path.

93146: sql/sem: add check for interval for asof.DatumToHLC() r=rafiss a=ZhouXing19

Currently, if the given interval for `AS OF SYSTEM TIME interval` is a small postive duration, the query can incorrectly pass. It's because when we call `clock.Now()`, it has passed the threashold ('statement timestamp + duration').

Now we add a check for the duration value. It has to be negative, with the absolute value greater than a nanosecond.

fixes #91021
link epic CRDB-17785

Release note (bug fix): add restriction for duration value for AS OF SYSTEM TIME statement.
