Make ignore counts work as "after stop" modifiers so they play nicely with conditions

Previously ignore counts were checked when we stopped to do the sync callback in Breakpoint::ShouldStop. That meant we would do all the ignore count work even when
there is also a condition says the breakpoint should not stop.

That's wrong, lldb treats breakpoint hits that fail the thread or condition checks as "not having hit the breakpoint". So the ignore count check should happen after
the condition and thread checks in StopInfoBreakpoint::PerformAction.

The one side-effect of doing this is that if you have a breakpoint with a synchronous callback, it will run the synchronous callback before checking the ignore count.
That is probably a good thing, since this was already true of the condition and thread checks, so this removes an odd asymmetry. And breakpoints with sync callbacks
are all internal lldb breakpoints and there's not a really good reason why you would want one of these to use an ignore count (but not a condition or thread check...)

[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.
