Subject: [PATCH] [HALX86] Re-enable HalpBiosDisplayReset() for x64: it
 actually supports display reset (#5513)

CORE-18185
Addendum to commit 215148267e7bad7

Everything that's needed (the x86 emulator with x86BiosCall) is implemented.
Fixes screen cleaning when bootvid takes over the VGA display.
