ESQL: Speed up TO_IP (#126338) (#126431)

Speed up the TO_IP method by converting directly from utf-8 encoded
strings to the ip encoding. Previously we did:
```
utf-8 -> String -> INetAddress -> ip encoding
```

In a step towards solving #125460 this creates three IP parsing
functions, one the rejects leading zeros, one that interprets leading
zeros as decimal numbers, and one the interprets leading zeros as octal
numbers. IPs have historically been parsed in all three of those ways.

This plugs the "rejects leading zeros" parser into `TO_IP` because
that's the behavior it had before.

Here is the performance:
```
Benchmark               Score    Error  Units
leadingZerosAreDecimal  14.007 ± 0.093  ns/op
leadingZerosAreOctal    15.020 ± 0.373  ns/op
leadingZerosRejected    14.176 ± 3.861  ns/op
original                32.950 ± 1.062  ns/op
```

So this is roughly 45% faster than what we had.

This includes a big chunk of #124676 - but not the behavior change -
just the code that allowed it.
