[Dexter] Fix test failures on greendragon (#66299)

The issue with these test failures is that the dSYM was not being found
by lldb, which is why setting breakpoints was failing and lldb quit
without performing any steps. This change copies the dSYM to the same
temp directory that the executable is copied to.

Re-reapply "[Dexter] Remove builder from Dexter"

This patch makes a further attempt to fix the tests broken by the
previous revision by ensuring that the command line for the modified
Dexter tests use -std=gnu++11, in keeping with the old build script.

This reverts commit 5647f2908de90fe07b0805e988cd2e91a1751928.

Revert "Reapply "[Dexter] Remove builder from Dexter""

Re-application of the Dexter builder removal reversed due to continued
errors on the green dragon LLDB buildbot:
https://green.lab.llvm.org/green/view/LLDB/job/lldb-cmake/59716/

Cause of the error is unclear, but it looks as though there is some
unexpected non-determinism in the test failures.

This reverts commit 323270451d8db24f2c816f455b3d8f70f434286d.

and 0b72b71cd3c8ad824342c05bc6d9d64d87eeb81b.

Failures occurred on two buildbots, the SIE buildbot:
https://lab.llvm.org/buildbot/#/builders/216/builds/26006

And the green dragon buildbot:
https://green.lab.llvm.org/green/view/LLDB/job/lldb-cmake/59091

Errors appear to be related to incorrect tool substitution in the Dexter
test commands, and a currently unknown error with one of the general
debuginfo tests that uses Dexter.

[Dexter] Remove builder from Dexter

See "discussion":
https://discourse.llvm.org/t/rfc-dexter-feature-removals/60462

This patch removes the builder functionality from Dexter, as it is an active
maintenance burden and is no longer required since Dexter is being invoked by
other test runners that can handle the build step better, and there has been no
objection that it is still needed.

[NFC][Py Reformat] Reformat python files in the rest of the dirs

This is an ongoing series of commits that are reformatting our
Python code. This catches the last of the python files to
reformat. Since they where so few I bunched them together.

Reformatting is done with `black`.

If you end up having problems merging this commit because you
have made changes to a python file, the best way to handle that
is to run git checkout --ours <yourfile> and then reformat it
with black.

If you run into any problems, post to discourse about it and
we will try to help.

[Dexter] Add timeout options

Adds a pair of options for Dexter that allow the user to specify a

* --timeout-total: Times out if the total run-time of the debugger session
exceeds <timeout-total> seconds.
* --timeout-breakpoint: Times out if the time without hitting a
breakpoint exceeds <timeout-breakpoint> seconds.

[Dexter] Allow tests to specify command line options

This patch adds a "DexCommandLine" command, allowing dexter tests to
specify what command line options the test should be started with. I've
also plumbed it through into the debuggers.

This eases the matter of pointing Dexter at larger tests, or controlling
different paths through a single binary from a Dexter test.

This patch adds a command, DexFinishTest, that allows a Dexter test to

same set of arguments as DexLimitSteps, except that it does not allow a
line range (from_line, to_line), only a single line (on_line).
