* crypto: add bls12-381 elliptic curve wrapper

* params: add bls12-381 precompile gas parameters

* core/vm: add bls12-381 precompiles

* core/vm: add bls12-381 precompile tests

* go.mod, go.sum: use latest bls12381 lib

* core/vm: move point encode/decode functions to base library

* crypto/bls12381: introduce bls12-381 library init function

* crypto/bls12381: import bls12381 elliptic curve implementation

supress warning for inp that used in asm

* add mappings tests for zero inputs

fix swu g2 minus z inverse constant

* crypto/bls12381: fix typo

* crypto/bls12381: better comments for bls12381 constants

* crypto/bls12381: swu, use single conditional for e2

* crypto/bls12381: utils, delete empty line

* crypto/bls12381: utils, use FromHex for string to big

* crypto/bls12381: g1, g2, strict length check for FromBytes

* crypto/bls12381: field_element, comparision changes

* crypto/bls12381: change swu, isogeny constants with hex values
