IMPALA-9709: Remove Impala-lzo from the development environment

This removes Impala-lzo from the Impala development environment.
Impala-lzo is not built as part of the Impala build. The LZO plugin
is no longer loaded. LZO tables are not loaded during dataload,
and LZO is no longer tested.

This removes some obsolete scan APIs that were only used by Impala-lzo.
With this commit, Impala-lzo would require code changes to build
against Impala.

The plugin infrastructure is not removed, and this leaves some
LZO support code in place. If someone were to decide to revive
Impala-lzo, they would still be able to load it as a plugin
and get the same functionality as before. This plugin support
may be removed later.

Testing:
 - Dryrun of GVO
 - Modified TestPartitionMetadataUncompressedTextOnly's
   test_unsupported_text_compression() to add LZO case
