Expose profile_file in render settings

[TomMinor]

Describe the feature you'd like It would be handy to be able to set the profile file from within Solaris

Describe the solution you'd like ASTR(profile_file) already exists, it just needs exposing like ASTR2(profile_file, "profile:file") so it shows up in the render settings

Describe alternatives you've considered A clear and concise description of any alternative solutions or features you've considered.
