-->
Fixes a bug preventing derived logical plans from running in MySQL due to a
requirement that every derived table must have an alias:
> The [AS] tbl_name clause is mandatory because every table in a FROM clause
must have a name.
## What changes are included in this PR?
<!--
There is no need to duplicate the description in the issue here but it is
sometimes worth providing a summary of the individual changes in this PR.
-->
Includes a dialect update to specify whether derived tables require aliases.
For dialects that do, set a static alias. I've simply selected the name of the
operation prefixed with `derived_`, like `derived_sort`, etc.
## Are these changes tested?
<!--
We typically require tests for all PRs in order to:
1. Prevent the code from being accidentally broken by subsequent changes
2. Serve as another way to document the expected behavior of the code
If tests are not included in your PR, please explain why (for example, are
they covered by existing tests)?
-->
Yes
## Are there any user-facing changes?
<!--
If there are user-facing changes then we may require documentation to be
updated before approving the PR.

<!--
If there are any breaking changes to public APIs, please add the `api
change` label.
-->
No
