v4/ Add Config tools for AttachmentList

[lassopicasso]

Description (updated)

This PR enables the configuration of the AttachmentList v4. It consists of a dataTypeIds property, an array defining data types for displaying attachments, and has various combinations:

1. Specific data types - user-selected types for displaying attachments.
2. System-generated PDFs ["ref-data-as-pdf"] - for displaying PDFs containing overall app input.
3. All data types (excluding PDFs) [ ] or undefined - default, displays all attachments except PDFs.
4. All data types (including PDFs) ["include-all"] - similar to 3, but includes PDFs.
5. App developers can also choose between two process task options:
   • Default: Include data types from all process tasks.
   • Option: Include only data types from the current process task ["current-task"].

Implemented in Studio for various configurations:

• Switch 1: Current task (on) and all tasks (off - default).
• Switch 2: Include system-generated PDFs (on) and exclude them (off - default).
• Indeterminate checkbox: When checked, all available attachments in the combobox are selected.
• Combobox multiple: All available attachments.

Operates with two data structures:

1. External data (dataExternalFormat): Studio data saved to the backend. The function selectionIsValid prevents saving if no data types or reserved data type (PDF) are selected, displaying an error message.
2. Internal data (dataInternalFormat): Studio data used in the overall code.

Konverteringsfunksjonene er nå oppdatert og har tilpasset React-komponentene.

Møtte på en utfordring med onChangeTask, som førte til at jeg la til en funksjon handleDataTypesWhenCurrentTaskChange for å unngå krasj. Dette var nødvendig for å håndtere et case når currentTask gikk fra false til true mens alle vedlegg var valgt. Den oppdaterte ikke antall vedlegg valgt med bakgrunn i at det kun er nåværende oppgave som nå gjelder. Prøvde å håndtere denne logikken når dataen var på vei ut i convertInternalToExternalFormat, men må også oppdatere staten ellers ville combobox føre til at det krasjer. Jeg funderer på om det kan ha noe med at det ikke rekkes å rerendres før onValueChange i combobox blir trigget. Er et issue på det i designsystemet; https://github.com/digdir/designsystemet/issues/1640
