IMPALA-12684: Enable IMPALA_COMPRESSED_DEBUG_INFO by default

IMPALA_COMPRESSED_DEBUG_INFO was introduced in IMPALA-11511
and reduces Impala binary sizes by >50%. Debug tools like
gdb and our minidump processing scripts handle compressed
debug information properly. There are slightly higher link
times and additional overhead when doing debugging.

Overall, the reduction in binary sizes seems worth it given
the modest overhead. Compressing the debug information also
avoids concerns that adding debug information to toolchain
components would increase binary sizes.

This changes the default for IMPALA_COMPRESSED_DEBUG_INFO to
true.

Testing:
 - Ran pstack on a Centos 7 machine running tests with
   IMPALA_COMPRESSED_DEBUG_INFO=true and verified that
   the symbols work properly
 - Forced the production of minidumps for a job using
   IMPALA_COMPRESSED_DEBUG_INFO=true and verified it is
   processed properly.
 - Used this locally for development for several months
