https://youtrack.jetbrains.com/issue/CMP-4883/Default-Proguard-rules-cause-release-task-failure-when-using-Material-3-instead-of-2-in-Compose-Desktop

Targeting 1.8.0

The rules was added by testing our current examples. The comprehensive
rules are only possible if we run [all tests with
ProGuard](https://youtrack.jetbrains.com/issue/CMP-3404/Run-all-Compose-tests-with-ProGuard-on).

Also, each rule wasn't investigated thoroughly, in some cases it might a
valid rule, in some cases a ProGuard bug.

The auto integration checks on CI will be added in
https://youtrack.jetbrains.com/issue/CMP-7970/Add-integration-checks-for-all-libraries.


## Testing
`./gradlew runRelease` works in:
- https://kmp.jetbrains.com
- all examples

## Release Notes
### Features - Desktop
- The default ProGuard version is set to 7.7.0
- If there are any new errors in the release build, update [the ProGuard
rules](https://www.jetbrains.com/help/kotlin-multiplatform-dev/compose-native-distribution.html#minification-and-obfuscation)
- A usual workaround is to add `-keep class` for the associated with
error class in "Location:"
- If the error contains `androidx.` package, it might a Compose bug,
please report in https://youtrack.jetbrains.com/issues/CMP. The `-keep
class` workaround should also work in this case.
- _(prerelease fix)_ `./gradlew runRelease` doesn't crash with
`java.lang.VerifyError`
