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.

LibCrypto: Protect the SignedBigInteger ctor against integer overflow
...
In particular, if given a value of -2147483648, we would invoke signed
integer overflow (which is UB).

LibCrypto: Do not trim leading zeros in export_data by default
...
This fixes the issue with the exported data having a leading zero,
causing RSA::encrypt to trim the block down, and ruining the encryption.
Fixes #2691 :^)

LibCrypto: Add a simple SignedBigInteger
...
This patchset adds a simple SignedBigInteger that is entirely defined in
terms of UnsignedBigInteger.
It also adds a NumberTheory::Power function, which is terribly
inefficient, but since the use of exponentiation is very much
discouraged for large inputs, no particular attempts were made
to make it more performant.
