Revert "[sanitizer] Add facility to print the full StackDepot"

This reverts commit 2ffaa9a.

There were 2 reported bot failures that need more investigation:

http://lab.llvm.org:8011/builders/sanitizer-windows/builds/69871/steps/stage%201%20check/logs/stdio

   This one is in my new test.

http://lab.llvm.org:8011/builders/sanitizer-x86_64-linux-fuzzer/builds/39187/steps/check-fuzzer/logs/stdio

   This one seems completely unrelated.
