2194dc477a Replace MBEDTLS_CHAR_x with MBEDTLS_BYTE_x 
The CHAR macros casted to an unsigned char which in this project
is garunteed to be 8 bits - the same as uint8_t (which BYTE casts
to) therefore, instances of CHAR have been swapped with BYTE and
the number of macros have been cut down

c94060c641 Add TLS 1.3 specific key to SSL transform conversion function 
This commit adds the TLS 1.3 specific internal function

```
  mbedtls_ssl_tls13_populate_transform()
```

which creates an instance of the SSL transform structure
`mbedtls_ssl_transform` representing a TLS 1.3 record protection
mechanism.

It is analogous to the existing internal helper function

```
   ssl_tls12_populate_transform()
```

which creates transform structures representing record
protection mechanisms in TLS 1.2 and earlier.

allowing to derive the secrets specific to each stage of
a TLS 1.3 handshake (early, handshake, application) from

70d7fb0c2d Don't hardcode TLS 1.3 labels in test cases 
ssl_tls1_3_keys.c exports a structure containing all labels used
in the TLS 1.3 key schedule, but the TLS 1.3 key scheduling unit
tests so far replicated those labels in the test file. In particular,
wrong label values in ssl_tls1_3_keys.c wouldn't have been caught
by the unit tests.

This commit modifies the TLS 1.3 key schedule unit tests to use
the TLS 1.3 labels as exported by ssl_tls1_3_keys.c. This not only
makes sure that those labels are correct, but also avoids hardcoding
their hex-encoding in the test file.

58c5cea73b Include common.h from ssl_tls13_keys.c 
`common.h` takes care of the logic of chosing the correct
configuration file, so we don't need to replicate it in
each source file.

be9d6648f8 Implement TLS 1.3 key derivation function HKDF-Expand-Label 
This commit introduces a new file library/ssl_tls13_key.c
which will subsequently be populated with functionality relating
to the TLS 1.3 key schedule.

Those functions are expected to be internal and are documented
in the internal header library/ssl_tls13_keys.h.

The first function to be implemented is the key expansion
function `HKDF-Expand-Label`. See the documentation in
library/ssl_tls13_keys.h for more information.
