Alex Hall 1864b7ba5d (core) Add BulkAddOrUpdateRecord action for efficiency
Summary:
This diff adds a new `BulkAddOrUpdateRecord` user action which is what is sounds like:

- A bulk version of the existing `AddOrUpdateRecord` action.
- Much more efficient for operating on many records than applying many individual actions.
- Column values are specified as maps from `colId` to arrays of values as usual.
- Produces bulk versions of `AddRecord` and `UpdateRecord` actions instead of many individual actions.

Examples of users wanting to use something like `AddOrUpdateRecord` with large numbers of records:

I tested what made many `AddOrUpdateRecord` actions slow in the first place. It was almost entirely due to producing many individual `AddRecord` user actions. About half of that time was for processing the resulting `AddRecord` doc actions. Lookups and updates were not a problem. With these changes, the slowness is gone.

The Python user action implementation is more complex but there are no surprises. The JS API now groups `records` based on the keys of `require` and `fields` so that `BulkAddOrUpdateRecord` can be applied to each group.

Test Plan: Update and extend Python and DocApi tests.
