Replace GUARDED_BY with ABSL_GUARDED_BY in preparation for abseil upgrade (#2283)

Summary: Replace `GUARDED_BY` with `ABSL_GUARDED_BY` in preparation for
abseil upgrade

In order to upgrade to bazel 7, many of our dependencies (bazel repos)
need to be upgraded. In a branch that builds the pixie repo with bazel
7, this was a supporting change I needed to get the build working.
abseil/abseil-cpp@ba7a9e2
is where abseil removed the versions of the macro pixie used previously.

Relevant Issues: #2282

Type of change: /kind cleanup

Test Plan: Build should succeed
