Use D3D12's QueryDeviceVideoMemoryInfo to get the OS-determined process budget. Also introduces an export for reserving some amount of process memory - which keeps Dawn from using the entire process's budget. Bug: dawn:193 Change-Id: I6c17bd703d7cb24759bcee89c03add46944fec8c Reviewed-on: https://dawn-review.googlesource.com/c/dawn/+/16383 Reviewed-by: Austin Eng <enga@chromium.org> Commit-Queue: Corentin Wallez <cwallez@chromium.org>
