…dencies (#2044)

Add comprehensive nil checks in getFuncDoc function to handle incomplete
AST nodes from dependency packages. This resolves segmentation faults
that occur when parsing standard library types like atomic.Int32,
json.scanner, and ecdh.PrivateKey with ParseDependency enabled.

- Check for empty astDecl.Specs before accessing astDecl.Specs[0]
- Check for empty astDecl.Values before accessing astDecl.Values[0]
- Add nil checks for value.Obj and value.Obj.Decl chain

Fixes critical crash when parsing projects with dependencies.

* Improve named enum testing.

* `x-enum-descriptions` should have same length as `enum` array.

Otherwise, there's no way to know which descriptions corresponds to
which enum value.

* Update TypeSpecDef.Alias() to use standard nameOverride() function.

* Fix enum test.

* Remove name override from TypeSpecDef.TypeName() method.

As per PR #1866, the name override functionality has been removed from
TypeName() and put into Alias() which is used by SetSchemaName().

* Fixed struct naming when using dependency parsing

* Fixed naming

* Fixed debug message always triggering
