Cleanup: Fix const warning with BLI_array_free
when you call the BLI_array_free macro with a const pointer you get a
warning when the macro calls `MEM_freeN` (warning C4090: 'function':
different 'const' qualifiers)
This was warning originating from
`smart_uv_project_calculate_project_normals` in `uvedit_unwrap_ops.c`
Normally we resolve these with a non const cast at the callsite
but given BLI_array_free is a macro not a function this is not
an option here and it has to be resolved in the macro.
