Use Kotlin Metadata in annotation scanning

[MikeEdgar]

Closes #1362

• Remove incorrect handling of @org.jetbrains.annotations.NotNull to mean a property is required.
• Process any @kotlin.Metadata annotations present on a class when kotlinx-metadata-jvm dependency is present.
• Update testsuite/data test to no longer use an uber-jar or require a separate Jandex index by using a new @QuarkusTest profile
• Update testsuite/data compiler execution settings to account for requirements of Eclipse m2e plugin that uses the default-compile execution of maven-compiler-plugin to obtain the project's Java version.
