Restructure and overhaul entire Kotlin codebase

This commit introduces a complete architectural refactoring of the
Kotlin-based interception logic, based on the source of
1. https://github.com/5ec1cff/TrickyStore
2. https://github.com/beakthoven/TrickyStoreOSS

The primary purpose of this code is to intercept binder transactions to
the Android Keystore and KeyMint services. The overall workflow operates
in conjunction with a native library (injected via ptrace). The native
library hooks the binder's `transact` function and forwards pre- and
post-transaction events to the Kotlin side. This Kotlin code contains
all the high-level logic for parsing parameters, patching certificates,
and generating simulated keys.

The codebase is now organized into a clear, package-based architecture:

- attestation: Manages the creation and patching of ASN.1 attestation
  data structures.
- config: Handles loading and observing configuration files from disk.
- interception: Contains the core binder interception framework and its
  specific implementations for legacy Keystore (Android Q/R) and modern
  KeyMint/Keystore2 (Android S+).
- logging: Provides a centralized and consistent logging utility.
- pki: Manages Public Key Infrastructure, including certificate
  generation, parsing of key store XML files, and cryptographic helpers.
- util: Contains Android-specific utility functions for device properties.

This refactoring focuses on establishing a robust and extensible
architecture. The fine-tuning of the interception logic itself,
especially for corner cases in key generation and patching, is currently
under redesign and will be further refined in subsequent commits.
