[WIP]x86: Introduce the blobolator

This is a PoC to run arbitrary code and blobs inside an emulated
virtual machine using libx86emu, thus the name blobolator.

The libx86emu has been patched to the following:
* redirect IO to the host machine it's running on
* trace IO
* start in protected mode
* add mechanism to drop IO access
* add Kconfig to debug code it is running

Implemented features:
* Run ramstage in libx86emu
* Run postcar in libx86emu

TODO:
* Add support to trace only blobs, not stages.
* Improve translation of known IO to human readable format
** COM
** PCI
** APIC
** PIT
** POST

Tested on qemu. Sucessfully run ramstage in blobolator.
