Subject: Implement HLE macro for DrawElementsIndirect (#3748)
* Implement HLE macro for DrawElementsIndirect
* Shader cache version bump
* Use GL_ARB_shader_draw_parameters extension on OpenGL
* Fix DrawIndexedIndirectCount on Vulkan when extension is not supported
* Implement DrawIndex
* Alignment
* Fix some validation errors
* Rename BaseIds to DrawParameters
* Fix incorrect index buffer and vertex buffer size in some cases
* Add HLE macros for DrawArraysInstanced and DrawElementsInstanced
* Perform a regular draw when indirect data is not modified
* Use non-indirect draw methods if indirect buffer was not GPU modified
* Only check if draw parameters match if the shader actually uses them
* Expose Macro HLE setting on GUI
* Reset FirstVertex and FirstInstance after draw
* Update shader cache version again since some people already tested this
* PR feedback
