Remove MBEDTLS_ECP_MAX_MPI_BYTES macro

Browse Source 
Remove MBEDTLS_ECP_MAX_MPI_BYTES macro as
it's not needed anymore.It was added when
memcpy was being used but now that
mbedtls_mpi_write_binary() is being used
it can handle copying a large buffer filled
with leading zeros into a smaller buffer.
