[Bug]: container test_allocator should be skipped if testing is disabled

[here-abarany]

Describe the issue

If testing is disabled, I would expect all dependencies on googletest to be removed. However, the internal test_allocator target inside of the container directory still gets created, which expects the GTest::gmock target to exist. As a result, if googletest isn't available, a CMake error will be raised due to the gmock target not existing.

Steps to reproduce the problem

Run CMake with testing disabled on a system without googletest installed.

I'm seeing the same thing. I suspect that a change in a recent version of cmake (possibly 3.30.0) as identical code built with earlier versions of CMake isn't failing.

It seems that the problem is fixed in the main branch, c.f. these issues:
open-telemetry/opentelemetry-cpp#2998
#1536

Alternatively, commenting out line 215 "GTest::gmock" in absl/container/CMakeLists.txt works.

It looks like this has been fixed.
