fmt: allow uppercase prefix to be parsed in std.fmt.parseInt()

std.fmt.parseHexFloat allow both 0x and 0X as prefix, so in order to keep things consistent. This commit modifies std.fmt.parseWithSign to check for the prefix case insensitively in order to allow both upper case and lower case prefix. This change now allows: 0O, 0B and 0X as prefixes for parsing.
