It feels weird using GL_* enums in a Vulkan driver.

The vertex order is either clockwise or counterclockwise. We can just
store a "ccw" boolean rather than GLenum values. I don't want to use
GLenums in a Vulkan driver, and even in GL a simple boolean works fine.

This will be used in api_validate.c in a following patch when we
switch to using gl_program pointers for the pipelines CurrentProgram
array.

This will allow us to simplify the current program logic for SSO.
Also since we aim to detach shader_info from nir_shader this will come
in handy avoiding passing nir_shader around just to keep track of
the stage we are dealing with.
V2: set stage for arb asm programs also.

This extension allows the fragment shader to control whether values in
gl_SampleMaskIn[] reflect the coverage after application of the early
depth and stencil tests.

We switched from a boolean to array lengths in gl_program a while back.

This function is added here to ease refactoring towards using the new shared
shader_info. Once refactoring is complete and values are set directly it
will be removed.
We call it from _mesa_copy_linked_program_data() rather than glsl_to_nir()
so that the values will be set for all drivers. In order to do this some
calls need to be moved around so that we make sure to call
do_set_program_inouts() before _mesa_copy_linked_program_data()

This will allow use to stop copying values between structs and
will also simplify handling handling these values in the shader cache.
