drm/amdgpu/vcn4.0.5: enable secure submission on unified ring

Browse Source 
Set secure_submission_supported = true for the VCN unified ring funcs in
vcn_v4_0_5.c so secure IBs are allowed on the unifiedring.
Without this, protected decode submissions are blocked by the
common IB gate and can fail playback for secure content.

For vcn_v4_0_5.c (fixed STX VCN version), secure submission is
enabled directly in the ring funcs definition.

This change only advertises existing hardware/firmware capability;
non-secure decode paths are unaffected.
