Campbell Barton 649b89781e Cleanup: ensure UTF8 string copy for DNA & screen data 
Use `BLI_strncpy_utf8` & `BLI_snprintf_utf8` for fixed size buffers in
DNA and screen data structures such as panels, menus & operators.

This could be considered a fix as copying a UTF8 string into a smaller
buffer without proper truncation can create an invalid UTF8 sequence.
However identifying which of these users are likely to run into would
be time consuming and not especially useful.
