[dawn-test] On D3D12, limit the texels in a buffer to 1<<27 

On D3D12, there is a limit of the number of texels in a buffer which is 1<<27. See D3D11_REQ_BUFFER_RESOURCE_TEXEL_COUNT_2_TO_EXP and the spec. This patch limits it according to the spec in case of D3D12 in MaxLimitTests.cpp. This fixes MaxLimitTests failure on Arm device.
