This commit adds support for using different `keybox.xml` files for different applications. This allows for greater flexibility, enabling the use of distinct cryptographic identities for specific groups of apps.
The `target.txt` configuration now supports a new syntax. A line with a filename in brackets, like `[demo_keybox.xml]`, sets the active keybox for all subsequent packages in the file.
The implementation refactors the configuration and keybox loading logic:
- PkgConfig now parses the new syntax and maps packages to their designated keybox files.
- KeyBoxUtils is updated to dynamically load and cache multiple keybox files on demand, instead of relying on a single global state.
- Certificate generation and hacking functions now use this new configuration to select the correct keybox for each operation based on the application's UID.
- Make use of waitForService() for >= Android 11.
- Reserve manual polling for Android 10 due to lack of waitForService().
- Rework on logs to be less cluttering.

The previous implementation used `pingBinder()` to check the liveness of the PackageManager service on every call to `getPm()`. This polling approach introduces an unnecessary IPC round-trip overhead for every access.
This commit refactors the logic to use the canonical, event-driven pattern for handling remote service death by implementing `linkToDeath`.
A `DeathRecipient` is now registered with the binder upon the first connection. If the service process (`system_server`) dies for any reason, the `binderDied()` callback is automatically invoked by the system. This callback proactively clears the cached service instance, ensuring that the next call to `getPm()` will transparently re-establish a valid connection.
- Reuse and extend the attestation we perform for detection of functional TEE.
- Extract properties like boot hash, os version, attest version, keymaster version from the generated certificate.
- Use previous methods as fallback for devices without functional TEE.
- Set ro.boot.vbmeta.digest during initialization with the boot hash value.

- We dont need the whole dev.rikka.hidden.stub library so just remove it and simplify dependencies.
- We already have our own stub package so we can just include the missing stubs that we want directly in it.
