## Proposed changes
1. Added support to join JARs to the uber JAR with ProGuard, disabled by
default:
```
compose.desktop {
application {
buildTypes.release.proguard {
joinOutputJars.set(true)
}
}
}
```
2. All 'release' tasks now really depend on ProGuard, as stated in
[tutorial](https://github.com/JetBrains/compose-multiplatform/tree/master/tutorials/Native_distributions_and_local_execution#minification--obfuscation).
## Testing
- A new auto test
- Manual:
1. Test on Windows/macOs/Linux
2. Test the new Gradle parameter `joinOutputJars`:
```
compose.desktop {
application {
buildTypes.release.proguard {
joinOutputJars.set(true)
}
}
}
```
`false` (by default) should generate multiple jars (except for
`package*UberJarForCurrentOS`)
`true` should generate a single jar in a result distribution
3. Test debug tasks:
```
run
runDistributable
createDistributable
packageUberJarForCurrentOS
```
4. Test release tasks:
```
runRelease
runReleaseDistributable
createReleaseDistributable
packageReleaseUberJarForCurrentOS
```
The jars should be reduced in size (because Proguard is enabled in the
release mode)
This should be test by QA.

/** |

* This task flattens all jars from the input directory into the single one, |
||||
* which is used later as a single source for uberjar. |
||||
* |
||||
* This task is necessary because the standard Jar/Zip task evaluates own `from()` args eagerly |
||||
* [in the configuration phase](https://discuss.gradle.org/t/why-is-the-closure-in-from-method-of-copy-task-evaluated-in-config-phase/23469/4) |
||||
* and snapshots an empty list of files in the Proguard destination directory, |
||||
* instead of a list of real jars after Proguard task execution. |
||||
* |
||||
* Also, we use output to the single jar instead of flattening to the directory in the filesystem because: |
||||
* - Windows filesystem is case-insensitive and not every jar can be unzipped without losing files |
||||
* - it's just faster |
