IMPALA-9731: Remove USE_CDP_HIVE=false and Hive 2 support

Impala 4 moved to using CDP versions for components, which involves
adopting Hive 3. This removes the old code supporting CDH components
and Hive 2. Specifically, it does the following:
1. Remove USE_CDP_HIVE and default to the values from USE_CDP_HIVE=true.
   USE_CDP_HIVE now has no effect on the Impala environment. This also
   means that bin/jenkins/build-all-flag-combinations.sh no longer
   include USE_CDP_HIVE=false as a configuration.
2. Remove USE_CDH_KUDU and default to getting Impala from the
   native toolchain.
3. Ban IMPALA_HIVE_MAJOR_VERSION<3 and remove related code, including
   the IMPALA_HIVE_MAJOR_VERSION=2 maven profile in fe/pom.xml.

There is a fair amount of code that still references the Hive major
version. Upstream Hive is now working on Hive 4, so there is a high
likelihood that we'll need some code to deal with that transition.
This leaves some code (such as maven profiles) and test logic in
place.

> We recently moved to use USE_CDP_HIVE=true by default, and Impala 4 intends to remove the CDH / Hive 2 code. We do not want to incur the overhead of maintaining this old support. This Jira tracks removing that code.
> USE_CDP_HIVE should be removed entirely, and the code should be the equivalent of what USE_CDP_HIVE=true is now.
