* Bump Gradle to 9.1.0
* Bump foojay resolver to 1.0.0
* Fix build logic on windows
Also, remove support for kotlin gradle plugin less than 1.8.x, because:
* Class `org.gradle.api.plugins.Convention` is no longer available in the classpath in Gradle
* Continued support for legacy plugin would require heavy reflection, which is brittle and hard to verify
* Kotlin 1.7 is 3 years old and no longer updated
Changes:
- Update wrapper by running the following command:
./gradlew wrapper --gradle-version 8.11 --gradle-distribution-sha256-sum

- Verify wrapper JAR integrity according to:
https://docs.gradle.org/current/userguide/gradle_wrapper.html#
manually_verifying_the_gradle_wrapper_jar
- Replace usages of deprecated method `Project.exec` with `ExecOperations.exec`
- Convert extension function `Task.configureInstallGraalVm` to task class `InstallGraalVm`
- a task class is the cleanest way to get hold of `ExecOperations`
- Move extension property `BuildInfo.GraalVm.downloadFile` into class `GraalVm`
- Don't apply plugin `pklGraalVm` in project `bench` (unnecessary, now causes error)
- Fix and clean up the pkl-commons-test build script.
- Change tests to read test packages/certs directly from
the file system instead of packaging and reading them
from the class path.
- Update expected checksums of some test packages.
- Fix a conflict between Pkl's and Gradle's
Kotlin libraries in the pkl-gradle project.
- Fix build deprecation warnings.
- Ensure Gradle distribution integrity with `distributionSha256Sum`.
- Manually verify integrity of Gradle wrapper added by this commit.
