feat(api): implement getIdentifier() to access tauri.conf.json identifier

[niladrix719]

Description

This PR adds a new getIdentifier() API function to access the application's bundle identifier from the frontend. This allows developers to access the identifier configured in tauri.conf.json without having to maintain a separate constant or parse the config file.

Closes #12753

Changes

• Added getIdentifier() function to the app API
• Added the command to the core:app plugin with default permissions
• Updated API example to demonstrate usage

Testing

• Added the function to the API example app
• Verified the returned identifier matches tauri.conf.json
• Cargo test passes
• Cargo clippy passes
• All commits are signed

API Example

import { getIdentifier } from '@tauri-apps/api/app';
const identifier = await getIdentifier(); // returns "com.tauri.api"

Nice, thank you! Can you also add a small changefile similar to https://github.com/tauri-apps/tauri/pull/9687/files#diff-e81fe1c50bf4d06ae9838270ec4f0bf64c36193d5d29c6c71fb523363ca57a7e ? (but just tauri and @tauri-apps/api)

p.s. CI is asking you to re-run pnpm build in packages/api and commit the generated files.

just a fyi, because 2.3.0 was just released i'll have to wait a bit before i can merge new minor prs. You don't have to do anything here anymore :)
