New C/Py api utility function PyC_Err_Format_Prefix() which raises an error with the existing error as a suffix.

Use this to raise errors when assigning a string property fails even though the value to assign *is* a string.


Before:
TypeError: bpy_struct: item.attr= val: Object.name expected a string type, not str


After:
TypeError: bpy_struct: item.attr= val: Object.name error assigning string, UnicodeEncodeError('utf-8' codec can't encode character 'udce9' in position 23: surrogates not allowed)
