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.
