Which targets are impacted by this bug?

DEBUG, RELEASE

Current Behavior

I think I've got the targets right, apologies if not.

With the QEMU Ramfb display, there are only very low resolutions available by default, which makes virtual machines that use this fairly sub-optimal. I think I know how to add resolutions to this, which I would be happy to do if that would be accepted. I suppose this might also be a problem for other display types, but I am not sure.

Expected Behavior

There are more standard screen resolutions available for the Ramfb display.

Steps To Reproduce

Create a new virtual machine using the Ramfb display, using the latest OVMF code, and observe that the support display resolutions are very low. I tested this with the latest stable release, but I can see in https://github.com/tianocore/edk2/blob/master/OvmfPkg/QemuRamfbDxe/QemuRamfb.c that the issue is still here.
