1) Clarify file and function header comments for the PE/COFF Extra Action library class

2) Update the file and function header comments in the BasePeCoffExtraActionLibNull
3) Add ASSERT() statements to APIs in BasePeCoffExtraActionLibNull is ImageContext is NULL.

Provides services to perform additional actions to relocate and unload
PE/Coff image for some environment specific purpose say for souce level debug.
Provides services to perform additional actions when a PE/COFF image is loaded
or unloaded. This is useful for environment where symbols need to be loaded
and unloaded to support source level debugging.
