Support modifiers on types in parser

Browse Source 
(required for 'suspend' on functional types).

TYPE_REFERENCE element now has MODIFIER_LIST child, which hosts annotations and modifiers for the corresponding type reference.

Annotations and modifiers written before an extension function type are now parsed as annotations and modifiers for the functional type, not the receiver type.
So, '@Ann A.(B) -> C' was '(@Ann A).(B) -> C', and became '@Ann (A.(B) -> C)'.
NB: DSL_SCOPE_VIOLATION testData updated accordingly.

Type projection variance modifiers ('in', 'out') belong to a separate modifier list under corresponding type projection (not under a type reference).
'A<in suspend T>' is 'A<(in (suspend T))>', 'A<suspend in T>' is an error.

In stub builder, create a modifier list node to host annotations and modifiers (none so far; TODO properly serialize/deserialize types with modifiers).
