feat!: Sync icon list with extension

[FrederikBolding]

Sync the icon list with the current list from the extension. This includes breaking changes as some icons were removed.

Closes #3652

---

Note

Syncs the IconName enum to the extension (many additions, some removals/renames causing breaks) and updates an example snap manifest shasum.

• SDK:
  • Icon list sync: Updates IconName in packages/snaps-sdk/src/jsx/components/Icon.ts to match the extension.
    • Adds numerous icons (e.g., Accessibility, Ai, ArrowCircleDown, CloudUpload, Exchange, HomeFilled, Send, StarFilled, Verified, WalletFilled, etc.).
    • Removes/renames legacy entries (e.g., Send1/Send2, Import, NotificationCircle, LockCircle, SecurityCard, CardToken, BankToken, Custody, UserCircleLink, PlusMinus, Timer, Tilde, etc.).
    • Includes breaking changes due to removed/renamed enum values.
• Examples:
  • Update packages/examples/packages/send-flow/snap.manifest.json source.shasum.
