Michael Smith d217b9ecc6 IMPALA-14450: Simplify Java version selection ...

Removes IMPALA_JAVA_HOME_OVERRIDE and updates version selection. In
order of priority
1. If IMPALA_JDK_VERSION is set, use the OS JDK version from a known
   location. This is primarily used when also installing the JDK as part
   of automated builds.
2. If JAVA_HOME is set, use it.
3. Look for the system default JDK.

The IMPALA_JDK_VERSION variable is no longer modified to avoid issues
when sourcing impala-config.sh multiple times. JAVA_HOME will be
modified if IMPALA_JDK_VERSION is set; both must be unset to restore
using the system default Java.

If switching between JDKs, now prefer setting JAVA_HOME. If relying on
system Java, unset JAVA_HOME after e.g. update-java-alternatives.

The detected Java version is set in IMPALA_JAVA_TARGET, which is used to
add Java 9+ options and configure the Java compilation target.

Eliminates IMPALA_JDK_VERSION_NUM as it's value was always identical to
IMPALA_JAVA_TARGET.

Stops printing from impala-config-java.sh. It made the output from
impala-config.sh look strange, and the decisions can all be clearly
determined from impala-config.sh printed variables later or the packages
installed in bootstrap_system.sh.

Fixes JAVA_HOME in bootstrap_build.sh on ARM64 systems.
