execinfra: correctly propagate processorID for LocalProcessors

[yuzefovich]

Previously, this was incorrectly hard-coded as zero. The impact of this seems minor (I believe this would only make it so that we could incorrectly attribute ComponentStats object of planNodeToRowSource to the wrong processor), but I think it still deserves to be backported.

Epic: None

Release note: None

Encountered an error creating backports. Some common things that can go wrong:

2. There was a merge conflict.
3. The backport branch contained merge commits.

You might need to create your backport manually using the backport tool.
