device: Add new Kconfig VGA_ROM_RUN_DEFAULT for mainboard user

Platform can now select VGA_ROM_RUN_DEFAULT Kconfig to perform graphics
initialization for PCI-E based discrete card through VGA OpRom
(SoC or Mainboard user can't select VGA_ROM_RUN directly because
it's part of choice option).

(Note: Some payloads, like SeaBIOS, are also able to run Option ROMs,
so coreboot does not need to enable VGA_ROM_RUN Kconfig)

For payload like depthcharge, create VGA_ROM_RUN_DEFAULT Kconfig
for mainboard to select design with DGPU where OpROM is embedded
inside the DGPU card.

Allow auto selection of VGA_ROM_RUN_DEFAULT from VGA_BIOS Kconfig.

Also NO_GFX_INIT Kconfig to avoid running VGA_ROM_RUN
by default in case SeaBIOS is used.

TEST=Able to get Pre-OS splash screen with AMD Radeon RX 5700 PCI-E
DGPU when mainboard user selects VGA_ROM_RUN_DEFAULT.
