Workspace address: send discrete SetPolicyAddress params and keep legacy display compatibility

[c3024]

Problem

App still sends legacy nested params (data[addressStreet], etc.) for SetPolicyAddress, and still concatenates line 1 + line 2 into addressStreet with \n.

Parent issue: https://github.com/Expensify/Expensify/issues/394853

Solution

• Update SetPolicyAddress params to flat fields in:
  • src/libs/API/parameters/UpdatePolicyAddressParams.ts
  • src/libs/actions/Policy/Policy.ts
• Add addressStreet2?: string to CompanyAddress in:
  • src/types/onyx/Policy.ts
• Stop newline concatenation when submitting workspace address in:
  • src/pages/workspace/WorkspaceOverviewAddressPage.tsx
  • src/pages/Travel/WorkspaceAddressForTravelPage.tsx
• Update display/read compatibility to support both:
  • New format: addressStreet + addressStreet2
  • Legacy format: addressStreet containing \n
• Compatibility updates in:
  • src/pages/workspace/WorkspaceOverviewPage.tsx
  • src/pages/workspace/duplicate/WorkspaceDuplicateSelectFeaturesForm.tsx
  • src/libs/ReportActionsUtils.ts
  • src/pages/workspace/WorkspaceOverviewAddressPage.tsx (form prefill path)

This is not open for proposals. I am working on this.
