[BACKPORT]: lib: uuid: alignment error in gen_rand_uuid()

Packed structures like struct uuid are not aligned. GCC 9.1 therefore
throws an error when trying to compile gen_rand_uuid().

lib/uuid.c: In function ‘gen_rand_uuid’:
lib/uuid.c:244:2: error: converting a packed ‘struct uuid’ pointer
(alignment 1) to a ‘unsigned int’ pointer (alignment 4) may result in
an unaligned pointer value [-Werror=address-of-packed-member]
244 | unsigned int *ptr = (unsigned int *)&uuid;
| ^~~~~~~~

Generate the uuid in a properly aligned buffer.

The byte order of a random number should not matter. Do not call
cpu_to_be32() to change the byte order.

new commands: uuid and guid - generate random unique identifier

Those commands basis on implementation of random UUID generator version 4
which is described in RFC4122. The same algorithm is used for generation
both ids but string representation is different as below.

char: 0 9 14 19 24 36
xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
UUID: be be be be be
GUID: le le le be be

Commands usage:
- uuid [<varname>]
- guid [<varname>]

The result is saved in environment as a "varname" variable if argument is given,
if not then it is printed.

New config:
- CONFIG_CMD_UUID

lib: uuid: add functions to generate UUID version 4

This patch adds support to generate UUID (Universally Unique Identifier)
in version 4 based on RFC4122, which is randomly.

Source: https://www.ietf.org/rfc/rfc4122.txt

Changes:
- new configs:
- CONFIG_LIB_UUID for compile lib/uuid.c
- CONFIG_RANDOM_UUID for functions gen_rand_uuid() and gen_rand_uuid_str()
- add configs dependency to include/config_fallbacks.h for lib uuid.

lib/uuid.c:
- add gen_rand_uuid() - this function writes 16 bytes len binary representation
of UUID v4 to the memory at given address.

- add gen_rand_uuid_str() - this function writes 37 bytes len hexadecimal
ASCII string representation of UUID v4 to the memory at given address.

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 form

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.

This commit introduces cleanup for uuid library.
Changes:
- move uuid<->string conversion functions into lib/uuid.c so they can be
used by code outside part_efi.c.
- rename uuid_string() to uuid_bin_to_str() for consistency with existing
uuid_str_to_bin()
- add an error return code to uuid_str_to_bin()
- update existing code to the new library functions.
