bug-14365: add dynamic state to PSO
This commit covers phase 2 of the removal of dynamic
state objects. Now, an application can include an array
of VK_DYNAMIC_STATE_* values that tell the driver
which PSO dynamic state elements to use.
I.e. if VK_DYNAMIC_STATE_LINE_WIDTH was specified in the
pDynamicState array then the ICD should use the lineWidth
defined at PSO create time and ignore any set using
vkCmdSetLineWidth.
To accomplish that the driver will make a copy of the
dynamic state specified in the PSO as well as a bitmask
of the affected state. When vkCmdSet* is called, the
driver will check if a PSO override is current and ignore
the call if so.
At PSO bind time the command buffer's dynamic state
will be updated and the PSO override bitmask set so that
any future vkCmdSet*'s will be appropriately ignored.
TODO: Validation layer should probably indicate a warning
if app tries to do vkCmdSet on state defined by the PSO.
