Update build to use gradle wrapper 6.8 (7.x backport) (#67327)
- Updates our build to use the latest Gradle 6.8 release which is the last release before the major 7.0 release. - Resolve available gradle versions using built-in toolchain support - Fixes deprecated usage of JavaInstallationRegistry - We replace jdk handling in our build to rely on jvm detection provided by the gradle build tool itself. As we rely on environment variables pointing to jdks we wire this into the gradle jdk detection mechanism - Fix runtime jdk vendor detection used in fips.gradle (#67417) - Allow Current JDK as valid installation without requiring ENV setup (#67411) Co-authored-by: Mark Vieira <[email protected]>
