12cbefbee7 LibJS+LibCrypto: Use a bitwise approach for BigInt's as*IntN methods
This speeds up expressions such as `BigInt.asIntN(0x4000000000000, 1n)`
(#3615). And those involving very large bigints.

f49a55d089 LibCrypto: Update ModularInverse implementation to use extended GCD
The previous implementation of `ModularInverse` was flaky and did not
compute the correct value in many occasions, especially with big numbers
like in RSA.

Also added a bunch of tests with big numbers.
