ROCm/Windows gfx1151: per-process GPU VA space cap reproducer (hipMemAddressReserve / hipMemCreate share one ~256 GiB budget)

	"""Reproducer: per-process GPU virtual address space cap on ROCm/Windows.

	Three phases:

	1. VMM control - reserve 96 GiB, fill it entirely with 32 MiB
	hipMemCreate+Map+SetAccess. Expected: succeeds.
	2. VA-only - reserve 16 GiB windows in a loop until failure.
	Observed: stops at 240 GiB.
	3. Combined - reserve 229.2 GiB, then map 32 MiB pages into the last
	window. Observed: hipErrorOutOfMemory once
