xen/vmac: Delete STDINT block in vmac.h

Eclair reports that _MSC_VER is undefined, a MISRA Rule 20.9 violation.

This could be fixed by inserting an "&& defined(_MSC_VER)" clause, but the
whole block is entirely useless (it comments out the include of stdint) and
users pull in xen/types.h transitively.

Delete the whole block, and include xen/types.h to make it standalone.

No functional change.
