Added method that accepts vectorize header to be returned.

-1 do not want to code how the API returns this header in this PR, we are working on changes for how we do vecorize for the tables etc.

so lets make this PR just about what the embedding provider is doing

Setting value from the aggregated vectorize usage info.

for now just want it on the response object from calling the embedding provider

WIll remove the CDI related code.

+      return new Response(batchId, embeddings, new VectorizeUsageInfo(0, 0, 0, "", ""));


Added default VectorizeUsageInfo until all embedding provider class get refactored.

this is a record, so it has a constructor that will not enforce that VectorizeUsageInfo is non-null.

either: validate this in the canonical constructor or turn this into a class and validate in a ctor that takes all of the params

we should remove all the of() functions from the record, records should be simple structures with properties if they need a static factory they are prob not the right usage

Adapted the existing code to avoid compilation error in all the embedding providers. Will remove the of method for this record.

reasonable start, take out the Data API returning just make it the embedding provider for now because we are changing things, and some improvments on the code

this of() function has the same signature as the record constructor , why is it needed ?

can we also have the input and output tokens ?

Not sure if there is split like that in all the embedding api response. Will check.

Verified Not all provide these, Example cohere response is like `
"billed_units": {

2069 | "input_tokens": 2
2070 | },

`
Huggingface doesn't return any tokens size.

if we do not change the way of counting, and stick with this for an initial release, why not count both the request and the response in this function ?

Currently it is done considering there is only one vectorize per collection/table. Not sure of the code refactoring to support table's multi vectorize.
