Improve consitency throughout library/common.h

Browse source 
Replace the contents of MBEDTLS_PUT_UINTx_yz contained inconsitent
but similar/duplicate code to the MBEDTLS_BYTE_x macros. Therefore
the contents of the macros now utilise the byte reading macros.

MBEDTLS_PUT_UINT64_LE's written order was also not consitent with
the other PUT macros, so that was modified.

Documentation comment said LSB instead of MSB and that has also been
resolved.
