lib: uuid: code refactor for proper maintain between uuid bin and string

Changes in lib/uuid.c to:
- uuid_str_to_bin()
- uuid_bin_to_str()

New parameter is added to specify input/output string format in listed functions
This change allows easy recognize which UUID type is or should be stored in given
string array. Binary data of UUID and GUID is always stored in big endian, only
string representations are different as follows.

String byte: 0                                  36
String char: xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
string UUID:    be     be   be   be       be
string GUID:    le     le   le   be       be

This patch also updates functions calls and declarations in a whole code.
