Move version checking from Make into soong_ui

When kati keeps state around, it has to regenerate the ninja file every
time the state is changed. So move the java version checking into
soong_ui, where we can parallelize it with other operations instead of
only checking it occasionally.

Bug: 35970961
Test: Put java7 in PATH, m -j
Test: Put java8-google in PATH, m -j
Test: Put a space in TOP, m -j
Test: OUT_DIR=<case-preserving fs> m -j
Test: OUT_DIR=<path with space> m -j
Test: DIST_DIR=<path with sapce> m -j
