byte shifting opertations throughout library/ were only replaced with
the byte reading macros when an 0xff mask was being used.
The byte reading macros are now more widley used, however they have not
been used in all cases of a byte shift operation, as it detracted from
the immediate readability or otherwise did not seem appropriate.

Copy over the GET/PUT_UINT64_LE/BE macros from aes.c and sha512.c
Add the MBEDTLS_ prefix to all 4 macros.
Modify the GET_UINT64 macros to no longer take a target variable
as a parameter, so when the macro function is called it must be
assigned to a variable in the same statement.

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

aria.c has a shift by 3 bytes, but does not use the 0xff masking.
aparently this is not a problem and it is tidier to use the maco.

These cast to an unsigned char rather than a uint8_t
like with MBEDTLS_BYTE_x
These save alot of space and will improve maintence by
replacing the appropriate code with MBEDTLS_CHAR_x

The GET macros used to write to a macro parameter, but now
they can be used to assign a value to the desired variable
rather than pass it in as an argument and have it modified
in the macro function.
Due to this MBEDTLS_BYTES_TO_U32_LE is the same as
MBEDTLS_GET_UINT32_LE and was there for replaced in the
appropriate files and removed from common.h

The helper `mbedtls_ssl_write_handshake_msg` writes a handshake message
and updates the handshake transcript.
With TLS 1.3, we need finer control over the checksum: updating
at message granularity is not sufficient. To allow for manual maintenance
of the checksum in those cases, refine `mbedtls_ssl_write_handshake_msg()`
into `mbedtls_ssl_write_handshake_msg_ext()` which takes a parameter
determining whether the checksum should be updated.

- Improves readability
- Will be useful when we introduce MPS as an alternative msg layer.
- Will be useful when we need to reset the messaging layer upon
receipt of a HelloRetryRequest in TLS 1.3.

The AEAD additional data (AAD) is computed differently in TLS 1.3
compared to TLS 1.2, but this change hasn't yet been reflected in
the codee, rendering the current implementation of
```
mbedtls_ssl_{encrypt,decrypt}_buf()
```
not standard compliant.
This commit fixes this by adjusting the AAD extraction function
ssl_extract_add_data_from_record() and its call-sites.
Please see the documentation of the code for an explanation
of how the AAD has changed from TLS 1.2 to TLS 1.3.

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.
Signed-off-by: Hanno Becker <hanno.becker@arm.com>
In TLS 1.2 specific code, the internal helper functions
ssl_populate_transform() builds an SSL transform structure,
representing a specific record protection mechanism.
In preparation for a subsequent commit which will introduce
a similar helper function specific to TLS 1.3, this commmit
renames ssl_populate_transform() to ssl_tls12_populate_transform().
