[xenvbd PATCH 3/3] Enable KASAN build support

[Owen Smith <owen.smith@xxxxxxxxxx>]

KASAN (Kernel Address Sanitizer)
(see https://learn.microsoft.com/en-us/windows-hardware/drivers/devtest/kasan)
builds can be enabled when using the WDK 10.0.26100.2161 or later, and can be
used on specially prepared Windows 11 24H2 / Server 2025, or later, OSs.

KASAN enabled drivers should not generally deployed, as the OS needs to be
enabled, but these drivers can help track down illegal memory accesses and
similar issues.
