IMPALA-12005: Describe executor group set selection in query profile

This patch adds new profile counters under the Frontend profile node to
describe executor group set selection during query planning. It modifies
FrontendProfile.java to allow one level of TRuntimeProfileNode nesting
under the Frontend profile node. This makes it possible to group profile
counters specific to each executor group set in consideration. A new
"cpu-comparison" hint is added besides "fragment-cost" to help navigate
how cpu sizing decision is made.

This patch also adds some function overloading in runtime-profile.cc to
hide TotalTime and InactiveTotalTime that is meaningless for anything
under the Frontend profile node. Additional context also added into
AnalysisException threw when none of the executor group sets fits the
query requirement.

This is how the Frontend profile node looks like after running
TestExecutorGroups::test_query_cpu_count_divisor_fraction

    Frontend:
