Vincent Palatin 0d858f1544 curve25519: strip-down, build and test ...

Keep only the most compact version of the curve25519 code
and remove the remaining unused code for easier compilation.
Do the minimal changes to make it compile in the EC code base,
there should be no real functional changes.

Re-use the wording from BoringSSL include/openssl/curve25519.h for the
header.

TEST=run x25519 on host (ie 'make run-x25519')
and the STM32L4 target:
make BOARD=eve_fp PROJECT=x25519 TEST_BUILD=y
./util/flash_ec --board=eve_fp --image=build/eve_fp/x25519.bin
execute 'runtest' in the console.
