Since MinGW commit 395dcfdea ("rename hyper-v headers and def
files to lower case") [*], WinHvPlatform.h and WinHvEmulation.h
got respectively renamed as winhvplatform.h / winhvemulation.h.
The mingw64-headers package included in the Fedora version we
use for CI does include this commit; and meson fails to detect
these present-but-renamed headers while cross-building (on
case-sensitive filesystems).
Use the renamed header in order to detect and successfully
cross-build with the WHPX accelerator.
Note, on Windows hosts, the libraries are still named as
WinHvPlatform.dll and WinHvEmulation.dll, so we don't bother
renaming the definitions used by load_whp_dispatch_fns() in
target/i386/whpx/whpx-all.c.

Header guard symbols should match their file name to make guard
collisions less likely.
Cleaned up with scripts/clean-header-guards.pl, followed by some
renaming of new guard symbols picked by the script to better ones.

Support for xcr0 to be able to enable xsave/xrstor. This by itself
is not sufficient to enable xsave/xrstor. WHPX XSAVE API's also
needs to be hooked up.

Below is the updated version of the patch adding debugging support to WHPX.
It incorporates feedback from Alex Bennée and Peter Maydell regarding not
changing the emulation logic depending on the gdb connection status.
Instead of checking for an active gdb connection to determine whether QEMU
should intercept the INT1 exceptions, it now checks whether any breakpoints
have been set, or whether gdb has explicitly requested one or more CPUs to
do single-stepping. Having none of these condition present now has the same
effect as not using gdb at all.

Only leave the external interface in sysemu/whpx.h. whpx_apic_in_platform
is moved to a .c file because it needs whpx_state.

Rename the file in preparation for moving more implementation-internal
definitions to it. The build is still broken though.
