Provide extensibility to apply TagWith on internal EntityFinder queries (e.g., EntityEntry.GetDatabaseValues)

### What problem are you trying to solve?

We have a use-case where, by framework convention, every database query is required to include a TagWith() comment for traceability (e.g., debugging, profiling, audit trail).

This is easy for user-defined queries (dbContext.Set().TagWith(...)) but becomes a challenge for EF Core internal queries, like EntityEntry.GetDatabaseValues().

**Further technical details**
- EF Core version: 9.0.4
- Provider: SQL Server
- .NET 8.0

### Describe the solution you'd like

It would be helpful if EF Core provided an official extensibility point to influence system queries like these.

For example:

Make the creation of the _queryRoot query overridable or having protected instead of private _queryRoot, e.g., via a virtual method in EntityFinder.

Add a parameter to methods like GetDatabaseValues() to specify a tag string (similar to TagWith).
