Description of changes:
Android Studio Ladybug ships with an embedded JVM of 21.0.3. Since we were not being explicit in which JVM to use for compilation, this caused builds to fail because our Java code was being compiled with Java 21, while our Kotlin verison only supports up to Java 20.

I resolved this by explicitly setting the jvmToolchain to 17 for all gradle builds, regardless of whether it's from command line, on CI, or in the IDE.

I also had to disable the -Werror compiler option. It appears that this option was previously being disregarded, which has allowed many warnings to accumulate. Once these warnings are addressed then we can re-enable -Werror to prevent additional warnings from being introduced.

How did you test these changes?
