staging: csr: remove csr_utf16.c

Only one function was being used in the file, so move it to where it was
being called and delete the rest of the file, and csr_unicode.h as it's
no longer needed as well.

-/*******************************************************************************
-
-    NAME
-        CsrUtf8StrTruncate
-
-    DESCRIPTION
-        In-place truncate a string on a UTF-8 character boundary by writing a
-        null character somewhere in the range target[count - 3]:target[count].
-
-        Please note that memory passed must be at least of length count + 1, to
-        ensure space for a full length string that is terminated at
-        target[count], in the event that target[count - 1] is the final byte of
-        a UTF-8 character.
-
-    PARAMETERS
-        target - Target string to truncate.
-        count - The desired length, in bytes, of the resulting string. Depending
-                on the contents, the resulting string length will be between
-                count - 3 and count.
-
-    RETURNS
-        Returns target
