  Reapply "[lldb] Increase timeout on lldbutil.wait_for_file_on_target" (#190833)

Reapplication notes:
After reviewing the test failures that caused the original reverts, I'm
not convinced that this change is related. None of the test failures
failed while timing out waiting for a file.

Original Summary:
I've been tracking sporadic timeouts waiting for a file to appear on
macOS buildbots (and occasionally local development environments). I
believe I've tracked it down to a regression in process launch
performance in macOS.

What I noticed is that running multiple test suites simultaneously
almost always triggered these failures and that the tests were always
waiting on files created by the inferior. Increasing this timeout no
longer triggers the failures on my loaded machine locally.

This timeout moves from about 16 seconds of total wait time to about 127
seconds of total wait time. This may feel a bit extreme, but this is a
performance issue. While I was here, I cleaned up logging code I was
using to investigate the test failures.
