InOsEmuPkg: Make XIP work properly

Update the InOsEmuPkg to properly function with XIP. Make the Recovery FV read only. Remove the use of global variable writes from XIP code. Add a new global page that can be used in place of writting to the FD by XIP code. Think of this global page as a system SRAM.
