Improve App Performance and Startup Speed with Baseline Profiles and R8

[dymarow]

Integrating Baseline Profiles and R8 into the app could lead to noticeable performance gains. Here’s why:

• Baseline Profiles help pre-compile critical code paths, improving runtime performance.
• R8 provides advanced code shrinking and optimization, reducing APK size and making the app faster and more efficient.

Other apps, such as Reddit, have seen remarkable improvements in performance and startup times after implementing these tools. I believe M3UAndroid could benefit greatly from similar optimizations, especially for users who rely on quick and smooth access to their IPTV streams.

Changes Proposed:
This pull request includes:

1. A basic setup for Baseline Profiles to optimize critical user flows.
2. Configuration for R8 to enable code shrinking and optimization.
