Reinier van der Leer 9967b3a7ce fix(frontend/builder): Fix unnecessary graph re-saving (#11145)
- Resolves #10980
- 2nd attempt after #11075 broke some things

Fixes unnecessary graph re-saving when no changes were made after
initial save. More specifically, this PR fixes two causes of this issue:
- Frontend node IDs were being compared to backend IDs, which won't
match if the graph has been modified and saved since loading.
- `fillDefaults` was being applied to all nodes (including existing
ones) on element creation, and empty values were being stripped
*post-save* with `removeEmptyStringsAndNulls`. This invisible
auto-modification of node input data meant that in some common cases the
graph would never be in sync with the backend.

### Changes 🏗️

- Fix node ID handling
- Use `node.data.backend_id ?? node.id` instead of `node.id` in
`prepareSaveableGraph`
    - Also map link source/sink IDs to their corresponding backend IDs
  - Add note about `node.data.backend_id` to `_saveAgent`
  - Use `node.data.backend_id || node.id` as display ID in `CustomNode`

- Prevent auto-modification of node input data on existing nodes
- Prune empty values (`undefined`, `null`, `""`) from node input data
*pre-save* instead of post-save
- Related: improve typing and functionality of
`fillObjectDefaultsFromSchema` (moved and renamed from `fillDefaults`)

### Checklist 📋

#### For code changes:
- [x] I have clearly listed my changes in the PR description
- [x] I have made a test plan
- [x] I have tested my changes according to the test plan:
  - [x] Node display ID updates on save
- [x] Clicking save a second time (without making more changes) doesn't
cause re-save
- [x] Updating nodes with dynamic input links (e.g. Create Dictionary
Block) doesn't make the links disappear
