Inherit versioning info from environment if present
As the drivers stabilize and mature, there is an ever-growing
chance that other opensource virtualization projects will adopt
them. Allow external projects to inject their own versioning
into the drivers instead of hardcoding the latest winpv version.

Often times we only need to build a driver for a single
targeted architecture. Continue to build both by default,
but allow the user to specify one if desired.

Add check for empty List in FdoCsqPeekNextIrp.
Under certain situations, such as when input is being sent during driver
install or sleep transition, FdoCsqPeekNextIrp can be called with an
empty Fdo->List. In that case, FdoCsqPeekNextIrp dereferences the list
head and returns an invalid IRP; it should check for this error
condition.

Implement device power state transitions.
Implement device power state transition boilerplate so that xenhid can
release its interfaces before the system enters S3. Let hidclass handle
other power types.
These bugchecks have been observed in recent updates of Server 2019.
This patch, rather than replacing calls to MmAllocatePagesForMdlEx() with
calls to MmMapLockedPagesSpecifyCache(), just avoids passing
MM_DONT_ZERO_ALLOCATION to work round the bug.
The patch instead passes MM_ALLOCATE_FULLY_REQUIRED, which arguably should
have always been passed for allocations larger than a single page. It also
fixes a formatting issue.
NOTE: Nothing in XENHID currently calls __AllocatePages() so this patch is
not strictly necessary. However, in case a caller is added in future,
it is best to keep util.h in sync with the other drivers.

Remove revision.h and simplify coinst.c
XENHID is not a bus driver and, as such, does not need a revision.h. Nor
does it have to sanity check support for non-existent child drivers in
coinst.c.
NOTE: I've largely cribbed XENNET's coinst.c, since it is another example
of a leaf function driver.

Add PowerShell build scripts, version.vcxproj
Based on the sequence of commits to xenbus, add powershell scripts to
build the solution using the EWDK
version.vcxproj generates versioned files (version.h, xeniface.inf and
wmi.mof) using scripts/genfiles.ps1
Strips duplicated functionality from build.py toproduce consistant
builds between python and powershell.

Conditionally package DPInst
Since DPInst.exe is not shipped with the Windows Driver Kit 10, an
environment variable must point to local copies. Make the inclusion of
DPInst conditional on DPINST_REDIST being defined and that path
existing. This simplifies building packages which do not require DPInst
for installation, and removes a required step to create a working build.

Update util.h
XENHID does not use much of the functionality in util.h, including the
__AllocatePages() function modified by this change, however it is good to
keep the header in-sync with the other drivers.
