patch 9.1.1339: missing out-of-memory checks for enc_to_utf16()/utf16_to_enc()

Browse Source 
Problem:  missing out-of-memory checks for enc_to_utf16() and
          utf16_to_enc()
Solution: Add out-of-memory checks and fix a few other minor issues
          (John Marriott)

This change does:
-  add missing out-of-memory checks for enc_to_utf16() and
   utf16_to_enc()
-  add a small optimisation in mch_errmsg_c() and mch_msg_c() (in
   message.c) to only call STRLEN() if needed.
-  fix a memory leak in winpty_term_and_job_init() (in terminal.c).

closes: #17191
