  [MSVC] Allow declaration of multi-dim 'property' array fields

MSVC allows declaration of multi-dim arrays like this:

__declspec(property(get=GetX, put=PutX)) int x[][][];

This syntax can appear in generated typelib headers.

Currently clang errors on declarators like this since it forms an array
type of incomplete array. Rather than try to handle such a type, ignore
adjacent empty chunks so this is treated as if there was only one empty
array chunk (i.e. int x[]).

The functionality to handle multi-dim subscripts of property fields
already works, but only if declared as a single-dim array.
