Fix type parsing issues in ILLink and ILC (#104060)

Browse source 
- Fixes https://github.com/dotnet/runtime/issues/98955

   We will now produce a warning when a non-assembly-qualified type
   flows into a string location annotated with
   DynamicallyAccessedMembers, and we don't try to look up or mark the
   type (since we don't know which assemblies will be searched at
   runtime by the Type.GetType call).

- Fixes https://github.com/dotnet/runtime/issues/103906

   The ILLink intrinsic handling for `Type.GetType` will now look in
   corelib for generic arguments, matching native AOT.

This replaces the existing warning IL2105. This uses a new warning
instead of repurposing IL2105, because we already documented IL2105
and older versions of ILLink will produce it. Best to avoid any
confusion about them.

#### `IL2122`: Type 'typeName' is not assembly qualified. Type name strings used for dynamically accessing a type should be assembly qualified.
- The type name string passed to a location with `DynamicallyAccessedMembers` requirements was not assembly-qualified, so the trimmer cannot guarantee that the type is preserved. Consider using an assembly-qualified name instead.
```C#
// warning IL2122: Type 'MyClass' is not assembly qualified. Type name strings used for dynamically accessing a type should be assembly qualified.
GetTypeWrapper("MyClass");
class MyClass { }
// May be defined in another assembly, so at runtime Type.GetType will look in that assembly for "MyClass".
void GetTypeWrapper([DynamicallyAccessedMembers(DynamicallyAccessedMemberTypes.PublicParameterlessConstructor)] string typeName)
{
var type = Type.GetType(typeName);
}
```
