Feature: support for local precompiled binaries

[dakshsilence]

Enable the generation and integration of precompiled binaries for specific targets and save it locally in binary folder. This feature allows binaries to be built once for supported platforms and reused when using with flutter rust bridge, eliminating the need for consumers to compile source code locally.

Steps to use it

1. Create local precompiled binaries using command precompile-local-binaries

example command, change the values for your use.

flutter pub run bin/build_tool.dart precompile-local-binaries -v --manifest-dir ../../rust --android-sdk-location=/Users/asdf/Library/Android/sdk --android-ndk-version=28.0.12674087 --android-min-sdk-version=23 --temp-dir tempDir

2. Update cargokit_options.yaml

use_local_precompiled_binaries: true
use_precompiled_binaries: true

3. Use the package

When you share the flutter package, the developer will installed the package and when they try to run app, flutter_rust_bridge will use the precompiled binaries.
