[PATCH 15/18] UefiPayloadPkg/Library/PlatformBootManagerLib: Remove broken VGA detection

["Sean Rhodes" <sean@starlabs.systems>]

From: Patrick Rudolph <patrick.rudolph@9elements.com>

This fixes an issue where the framebuffer provided by coreboot or
slimbootloader will only work on the primary VGA device. If the
framebuffer corresponds to a different device the screen will stay black.
In addition, the code doesn't work for multiple graphic cards, has
reference to non existing functions, and is a duplication of common code.

Call EfiBootManagerConnectVideoController on every display device found,
not only the legacy VGA device. This is the same as OvmfPkg does.

Allows to display output on the framebuffer set up by firmware, which might
not be the VGA device.
