Add definition pg_attribute_aligned() for MSVC
Visual Studio 2015+ has support for a macro to control the alignement of
structures as of __declspec(align(#)), and this commit adds a definition
of pg_attribute_aligned() based on that. It happens that this was
already used in the implementation of atomics for MSVC. Note that there
is still no definition fo pg_attribute_packed(), so this does not impact
itemptr.h.
