freedreno/a6xx: bump varyings limit

GL_MAX_VARYING_COMPONENTS is bumped to 124 since it should
not include the components of gl_Position. (Same as in blob)

GL_MAX_*_OUTPUT_COMPONENTS is bumped to 128, only
GL_MAX_GEOMETRY_INPUT_COMPONENTS is 64. (Same as in blob)

Per GL 3.2 spec the minimum of:
 - GL_MAX_GEOMETRY_OUTPUT_COMPONENTS is 128
 - GL_MAX_FRAGMENT_INPUT_COMPONENTS is 128
 - others is 64

Per ARB_tessellation_shader the minimum of:
 - GL_MAX_TESS_CONTROL_*_COMPONENTS to be 128
 - GL_MAX_TESS_EVALUATION_*_COMPONENTS to be 128

Allows passing of:
 gl-3.2-minmax
 arb_tessellation_shader-minmax
