Currently we define a device path for each root bridge statically (for all
one of them). Since we'll want to create a dynamic number of root bridges,
replace the static device paths with a common template, embed the actual
device path into the private root bridge structure, and distinguish the
device paths from each other in the UID field (as required by ACPI).
This patch is best viewed with "git show -b".

The entry point function of this driver, InitializePciHostBridge(), and
the static storage duration objects it relies on, are speculatively
generic -- they nominally support more than one host bridges, but (a) the
code hardwires the number of host bridges as 1, (b) it's very unlikely
that we'd ever like to raise that number (especially by open-coding it).
So let's just remove the the nominal support, and simplify the code.

The source code is copied verbatim, with the following two exceptions:
- the UNI files are dropped, together with the corresponding UNI
references in the INF file,
- the INF file receives a new FILE_GUID.
The OVMF DSC and FDF files are at once flipped to the cloned driver.
