    meta: Add GLSL variant of _mesa_meta_GenerateMipmap() function

    This reduces the overhead of using the fixed function internally
    in the driver.

    V2: Use setup_glsl_generate_mipmap() and setup_ff_generate_mipmap()
        functions to avoid code duplication.
        Use glsl version when ARB_{vertex, fragmet}_shader are present.
        Remove redundant code.

    V3: Remove redundant border related code leaving the assertion.
