ast: the field `qualifier` of `TSImportType` shouldn't have a `IdentifierReference`

[Dunqing]

I just found out that the field qualifier of TSImportType is TSTypeName, so that there is an identifier reference. But this is wrong because TSImportType shouldn't have any reference.

oxc/crates/oxc_ast/src/ast/ts.rs

Lines 1353 to 1359 in fadbd93

	pub struct TSImportType<'a> {
	pub span: Span,
	pub argument: TSType<'a>,
	pub options: Option<Box<'a, ObjectExpression<'a>>>,
	pub qualifier: Option<TSTypeName<'a>>,
	pub type_arguments: Option<Box<'a, TSTypeParameterInstantiation<'a>>>,
	}

type A = import("./a").b.c
                       ^ This is an identifier reference now.

But can never reference it.

The type here is much more complicated than I thought. I also noticed that TSTypeName is supposed to have a this expression, otherwise you can get identifier reference for this in type Foo = typeof this.foo;.

Type for qualifier should probably be something else instead of TSTypeName ...
