Cloud Hypervisor is an open source Virtual Machine Monitor (VMM) that
runs on top of KVM. Cloud Hypervisor is implemented in Rust and is based
on the rust-vmm crates. See [1] to find more.

To support UEFI, Cloud Hypervisor is introduced here.
There are 2 parts to be considered to do this enablement, that is:
1. specific ACPI service implementation compared with qemu, there is no
device like Fw-cfg, so we have no elegant way to get the RSDP address.
A specific ACPI implementation is introduced here.

2. build configuration file for Cloud Hypervisor

Change log:

v3 to v4:
(1) remove Tpm support in dsc file
(2) refine Acpi table install code base on Sami's comments in v3

v2 to v3:
(1) reuse qemu's memory initialization lib as they are in nearly the same
memory laout.
(2) split Acpi implemetation into PlatformHasAcpi and
InstallAcpiTable.
(3) remove lots of dependencies from qemu like "*Fwcfg*" lib.
(4) lots of code cleanup work to let it more approach to edk2 code
style.

Sami, any thoughts on this code?
