Lazy IRQL feature has issues with interrupt delivery on VirtualBox, so disable it for now.
For the feature description, see commit d28eae967a
Meanwhile, merge and clean up APIC headers a bit
- Rename UP -> PIC. The "up" folder in fact contains the code for
managing the Intel 8259 PIC chip
- Move amd64/processor.c -> apic/processor.c. The code is not tied to
amd64
- Remove platform from "halinit*" files. They already reside in the
corresponding folder
- Create xbox.cmake based on legacy.cmake and pic.cmake
- Revive Xbox HAL files and add them to the build
- Fix boot with Xbox HAL, add missing parts from halinit_up.c
- Code style and debug logging improvements in pcibus.c
- Allow to choose Xbox HAL in usetup

There is no need to compile our DLLs as shared libraries since we are
managing symbols exports and imports through spec files.
On my system, this reduces the configure-time by a factor of two.
