[lldb][test] Fix TestCallBuiltinFunction.py

A constant __builtin_abs(-14) cannot be evaluated without a running target
as Clang now emits llvm.abs.*

[NFC][Py Reformat] Reformat python files in lldb

This is an ongoing series of commits that are reformatting our Python
code. Reformatting is done with `black` (23.1.0).

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.

[lldb] Introduce createTestTarget for creating a valid target in API tests

At the moment nearly every test calls something similar to
`self.dbg.CreateTarget(self.getBuildArtifact("a.out"))` and them sometimes
checks if the created target is actually valid with something like
`self.assertTrue(target.IsValid(), "some useless text")`.

Beside being really verbose the error messages generated by this pattern are
always just indicating that the target failed to be created but now why.

This patch introduces a helper function `createTestTarget` to our Test class
that creates the target with the much more verbose `CreateTarget` overload that
gives us back an SBError (with a fancy error). If the target couldn't be created
the function prints out the SBError that LLDB returned and asserts for us. It
also defaults to the "a.out" build artifact path that nearly all tests are using
to avoid to hardcode "a.out" in every test.

I converted a bunch of tests to the new function but I'll do the rest of the
test suite as follow ups.

Summary:
If we don't have a current frame then we can still run many expressions

[lldb] Allow expect_expr without a running target

Summary:
If we don't have a current frame then we can still run many expressions
as long as we have an active target. With this patch `expect_expr` directly
calls the target's EvaluateExpression function when there is no current frame.
