Feature/eng 3362/fix color management prefs disable

[rhdutta]

Changelog Description

Add support for activate_host_color_management setting in Maya's set_colorspace() function. When this setting is false, Maya's color management is now explicitly disabled.

Additional review information

Previously, only the workfile.enabled setting was checked, which would simply skip color management configuration but not disable it, leaving Maya with its default (enabled) state. This allows studios to explicitly disable color management via AYON settings rather than relying on Maya's default preferences.

Testing notes:

1. Set Maya imageio settings: activate_host_color_management: false, workfile.enabled: false
2. Launch Maya through AYON - verify color management is disabled in Preferences > Color Management
3. Set Maya imageio settings: activate_host_color_management: true, workfile.enabled: false
4. Launch Maya through AYON - verify color management state is unchanged (Maya defaults)
5. Set Maya imageio settings: activate_host_color_management: true, workfile.enabled: true
6. Launch Maya through AYON - verify color management is enabled with the configured render space, display, and view settings

I see the reasoning - but I'm wondering if it was indeed the intend to "fully disable it".

Usually disabling OCIO management from AYON meant that it's 'unmanaged' by AYON and not that it was force disabled. @jakubjezek001 @antirotor thoughts? I'm fine with having a way to force disable OCIO in Maya - I just wonder what the right 'settings' would be like?

E.g. globally having host management enabled but workfile flag disabled I think makes more sense to be the thing that sounds like "manage it, but disable it explicitly". But now this PR makes it seems like if host management is disabled then force disable it always?
