chore(a3p-integration): do special-case in `proposals/f:*/package.jso…

…n` (#10294)

_Incidental._

## Description

Don't use special-case `build:submissions` scripts in `a3p-integration/package.json`, instead use additional declarative proposal generation in the `proposals/*/package.json` files.

### Documentation Considerations

As documented in https://github.com/Agoric/agoric-sdk/blob/master/a3p-integration/README.md#generating-core-eval-submissions this approach takes advantage of the fact that the submission output relative directory is specified by the second argument in each `proposals/?:*/package.json` `"sdk-generate"` array entry.  Those entries are interpreted by the `build-all-submissions.sh` script, as executed by `cd a3p-integration && yarn build`, or more specifically, `cd a3p-integration && yarn build:submissions`.
