added a conservative rasterization state to the graphics pipeline and the dynamic states for it. i have tested it with my own project and everything seems to be working.

Changelog:

### Additions
- Support for the `ext_conservative_rasterization` extension.
- Support for the `extended_dynamic_state3_conservative_rasterization_mode` device feature.
- Support for the `extended_dynamic_state3_extra_primitive_overestimation_size` device feature.

A few VUIDs are not validated yet:

VUID-VkGraphicsPipelineCreateInfo-conservativePointAndLineRasterization-08892
VUID-vkCmdDraw*-conservativePointAndLineRasterization-07499 (for every draw command, using the vuids! macro again)

LukeP0WERS commented 4 months ago

not sure how to do VUID-vkCmdDraw*-conservativePointAndLineRasterization-07499

Note that ConservativeRasterizationState is an extension to RasterizationState, not to GraphicsPipelineCreateInfo. We should fix this before releasing.
