8576: Change LateBindQueryist to use mysql.NewSalt()
In preparation for refactoring the auth server interface in Vitess/GMS, this change makes LateBindQueryist call mysql.NewSalt() directly, instead of relying on the NewSalt() method on the MySQLDb instance (which internally calls mysql.NewSalt()).

2753: Fixes CTE issue with auth
This fixes the test introduced in:
- dolthub/go-mysql-server#2745

2750: Fix alter NULL enum value panic
2739: Embed the embedded.Tracer into memTracer, to fulfil the updated interface
I was trying to use this project go-mysql-server as a dependency alongside github.com/grafana/grafana-plugin-sdk-go/data. But the latter project depends on:
- go.opentelemetry.io/otel v1.31.0
- go.opentelemetry.io/otel/trace v1.31.0
  When I updated my go modules with go mod tidy I started to hit a compilation error:
```
# github.com/dolthub/go-mysql-server/test
/Users/samjewell/go/pkg/mod/github.com/dolthub/go-mysql-server@v0.18.1/test/mem_tracer.go:22:2: could not import go.opentelemetry.io/otel/trace/embedded (open : no such file or directory)
FAIL	github.com/grafana/poc-sql-expressions-embedded-sql/dolthub-go-mysql-server [build failed]

```
Hence this change 🙏

378: support set names binary syntax (no quotes)
syntax for: #8574
377: Fixed CTE issue with auth
Fixes the test introduced in:
- dolthub/go-mysql-server#2745
375: support multiple like tables

8574: set names binary fails. set names 'binary' succeeds. Seems unquoted collations in MySQL are supposed to work with set names
