Reduce usage of Marshal.PtrToStructure and Marshal.StructureToPtr (#3805)

Browse source 
* common: Make BinaryReaderExtensions Read & Write take unamanged types

This allows us to not rely on Marshal.PtrToStructure and Marshal.StructureToPtr for those.

* common: Make MemoryHelper Read & Write takes unamanged types

* Update Marshal.SizeOf => Unsafe.SizeOf when appropriate and start moving software applet to unmanaged types
