Pacth 1 adds a new definition, 'INVALID_GFN', so that GFN
values can use it, instead of the 'GPA_INVALID'.

Pacth 2 makes the definition of 'INVALID_GPA' shared by
different archs.

Both are tested by rebuilding KVM for x86 and for ARM64.

---
V4:
- Put the addition of 'INVALID_GFN' into a seperate patch.
V3:
- Added 'INVALID_GFN' and use it.
v2:
- Renamed 'GPA_INVALID' to 'INVALID_GPA' and modify _those_ users. 
v1:
