Refactor quick pick item generation into shared utilities and add multi-root workspace support to the clipboard path selection command

- regarding `apps/editor/src/commands/select-clipboard-paths-command.ts`; in a multi root-folder workspaces ask the user for what workspace paths are. It is because they are not workspace-prefixed by default.
- `apps/editor/src/commands/select-clipboard-paths-command.ts` should skip listing workspaces with 0 found paths.
- `apps/editor/src/commands/select-clipboard-paths-command.ts` should show number of found paths on workspaces in description e.g. "20 · /sdf/sadf/sdf"
- sometimes clipboard paths have proper workspace-name prefix
- in `apps/editor/src/commands/select-clipboard-paths-command.ts` allow going back to the list of workspaces, when appropriate.
- in `apps/editor/src/commands/select-clipboard-paths-command.ts`; in case when showing workspace selector, restore it once user accepts file selection, so they can continue with selections from other root folders
- restore showing separators with root folder names (don't restore any other behaviors) [Changes]
- we have some unwanted code repetitions, e.g. [Fragment]
