Ensures the rate limitation is respected for by root blob and data column sidecars requests. (#15981)

Browse Source 
* Set default value of `--blob-batch-limit` to 384.

So, using default values, `--blob-batch-limit * --blob-batch-limit-burst-factor = 384*3 = MAX_REQUEST_BLOB_SIDECARS = 1152.`

* `blobSidecarByRootRPCHandler`: Add rate limiting.

Bacause now the rate limiter validation is done before the request validation,
adapt `TestBlobsByRootValidation` consequently and add new specific tests for
`validateBlobByRootRequest` to cover the now untested case.

* Set default value of `--data-column-batch-limit-burst-factor` to 4.

So, using default values, `--data-column-batch-limit * --data-column-batch-limit-burst-factor = 4096*2 = MAX_REQUEST_DATA_COLUMN_SIDECARS_ELECTRA = 16384`.

* `validateDataColumnsByRootRequest`: Take a count instead of idents.

* `dataColumnSidecarByRootRPCHandler`: Add rate limiting.
