radv: fix optimizing needed states if some are marked as dynamic

radv: fix optimizing needed states if some are marked as dynamic

From the Vulkan spec 1.2.157:

    "VK_DYNAMIC_STATE_STENCIL_TEST_ENABLE_EXT specifies that the
     stencilTestEnable state in VkPipelineDepthStencilStateCreateInfo
     will be ignored and must be set dynamically with
     vkCmdSetStencilTestEnableEXT before any draw call."

So, stencilTestEnable should be ignored if dynamic. While we are
at it, fix depthBoundsTestEnable too.
