pvmfw: Extract pvmfw-specific code out of mmu.rs

Prepare the file to be moved to vmbase for re-use by

 - Extracting pvmfw-specific functions dealing with the appended data
   and setting up the initial dynamic PTs to memory.rs
 - Renaming PageTable::map_data to map_data_dbm and re-introducing
   map_data for PTEs that don't set the DBM bit
 - Documenting public functions
 - Implementing From<IdMap> for PageTable
 - Introducing a Result wrapping type
