devgianlu 9240d38273 LibCrypto+LibTLS+LibWeb: Store EC key size + refactor serialization ...

In order for public/private key serialization to work correctly we must
store the size of the key because P-521 cannot be stored as full words
inside `UnsignedBigInteger` and therefore is exported as the wrong
length (68 instead of 66).

This makes it also possible to refactor some methods and cleanup
constants scattered around.

Gets almost all import/export tests, expect the JWK ones that calculate
the public key on export. The `SECPxxxr1` implementation currently fails
to do calculations for P-521.
