With the replace_prop_blob functions we can safely replace the blob for
any property, without having to care about error handling ourselves.
This will for example allow overriding color management blobs, or for
kms_atomic set invalid mode blobs.
The color management blob functions are removed, they can now be
replaced by direct calls to replace the properties.
Changes since v1:
- Fix chamelium tests.
