(core) Moving nbrowser tests to grist-core

Summary:
Moving bulk of nbrowser tests to core. Some tests were split and only part of them were moved.
Tests that are left are either: not suitable for grist-core (like billing) or are failing during browser tests (are not reliable).
Four fixtures directory (uploads, docs, exports-csv/excel) where completely moved to grist-core and are linked as folders.
Those changes allows to add an nbrowser test in grist-core or in the main test folder without any need to link it or link a fixture document.

Other changes:
- testrun.sh has been modified, now it runs tests from both folders (test and core/test),
- TestServer used in grist-core is now adding sample orgs and users (kiwi and others),

Test modified
- SelectionSummary: now it is run on a bigScreen, it was failing randomly
- Billing.ts: relative paths were used
- DateEditor: added waitForServer - it was failing in browser mode
- FrozenColumns, ImportFromGDrive, Printing: updated import paths
- UserManager.ts: was split into two parts (it assumed limited products)
- ViewLayoutResize.ts: this test is still in main repo, it is still failing in browser mode tests

Test Plan: Existing
