Allow linker initialization of lazy instance
Using the initializer list construct = {0} allows the object to be linker initialized.
Modify the LazyInstance class design to make it a pod aggregate type that can be linker initialized this way. Also combines the instance and state members, in line with the Singleton<> class design.
Introduces a new LAZY_INSTANCE_INITIALIZER macro specifically for using to init all lazy instances + modify all existing callsites to use it. (Old code would no longer compile)
