Add panama implementations of byte-bit and float-bit script operations

[thecoop]

Resolves #117096

This gets about a 6-10x speedup:

Benchmark                                  (dims)  (docType)  (function)  (queryType)  (type)  Mode  Cnt    Score   Error  Units
DistanceFunctionBenchmark.benchmark          1024        BIT         DOT        FLOAT  BINARY  avgt    2  441.688          ns/op
DistanceFunctionBenchmark.benchmark          1024        BIT         DOT         BYTE  BINARY  avgt    2  357.740          ns/op
DistanceFunctionBenchmark.vectorBenchmark    1024        BIT         DOT        FLOAT  BINARY  avgt    2   48.748          ns/op
DistanceFunctionBenchmark.vectorBenchmark    1024        BIT         DOT         BYTE  BINARY  avgt    2   55.824          ns/op

Still need to determine if 128-bit versions are helpful

Could you add tests to ESVectorUtilTests ? I don't think the ones I have written there actually cover indices that are big enough to be vectorized.

The PR includes changes to ESVectorUtilTests that creates random vectors up to 1024 dims

Hi @thecoop, I've created a changelog YAML for you.

marked it as enhancement as its a performance improvement :)
