[NTOS:IO] Minor formatting for IopSuffixUnicodeString and IopDisplayLoadingMessage.

Browse source 
- Doxygen comments;
- SAL annotations;
- These two functions are local to driver.c file only -> static'ify them.
- 2 -> sizeof(WCHAR);
- Rename Length to NumChars;
- static const'ify the L".SYS" string.
