LibCore: Change DateTime format strings to be StringViews

Browse source 
There's no need to allocate a String for these. Note the "string"
parameter of DateTime::parse is left as a String for now; the parser is
currently using strtol which needs a NUL-terminated string. This method
can likely be rewritten with GenericLexer.
