Escape constant names in queries

The `any` keyword was introduced in Go 1.18, and can be used in place
of `interface{}`. This was not in the list of reserved keywords, leading
to identifiers using this term in generated code.

Update the logic to escape constant names, and also add `any` to the
list of reserved keywords.
