cms-helper/static: Add "identity" builtin cms profile (v3)
Allows to force loading an identity gamma table if
option icc_profile= is given in weston.ini for
an output, ie., icc_profile= is specified to an
empty assignment.
Some special display output devices, e.g., for
neuro-science applications, and special display
testing hardware need a guaranteed perfect pixel
passthrough from framebuffer to output. This is
an easy way to set this up for cms-static.
v2: Remove confusing/redundant weston_log debug output.
v3: Don't use the "identity" keyword to trigger this, but
instead assignment of an empty string will trigger
loading of an identity LUT. Suggested by Derek Foreman.
