Cleanup: Use higher level semantic for zeroing DNA objects in C++

Replaces old-style memzero-style of call with zero-initializer.
Allows to shorten typical initialization code to a single line:

  Object foo = blender::dna::shallow_zero_initialize<Object>()

This will allow to more easily convert designated initializer
which is often used to fill object with zeroes to the explicit
function calls:

  MyDNAStruct foo = {};

will be translated to

  MyDNAStruct foo = blender::dna::shallow_zero_initialize<MyDNAStruct>();
