Run CodeQL for every language on hosted runners, Kotlin with a build

Default setup analyses Java without a build and leaves out every Kotlin file, and the Java job on the
self-hosted runner stopped at the NDK install because sudo asks for a password, so Kotlin had not been
analysed since February. One matrix job covers actions, JavaScript/TypeScript, Rust and Java/Kotlin.
