59237bb52c changed the behavior of the `SetTimeout` and `GetTimeout` methods of `EvaluateExpressionOptions`, which broke the Mojo REPL and related services (https://docs.modular.com/mojo/) because it relies on having infinite timeouts. That's a necessity because developers often use the REPL for executing extremely long-running numeric jobs. Having said that, `EvaluateExpressionOptions` shouldn't be that opinionated on this matter anyway. Instead, it should be the responsibility of the evaluator to define which timeout to use for each specific case.

This has failed once in a while on our Windows on Arm bot:

We're not here to check that Python/the C++ lib/the OS implemented
timers correctly, so accept anything 0.95 or greater.
Check the interrupt flag while interpreting IR expressions and allow the
user to interrupt them.

At the moment the IRInterpreter will stop interpreting an expression
after a hardcoded 4096 instructions. After it reaches the limit it will
stop interpreting and leave the process in whatever state it was when
the timeout was reached.
This patch changes the instruction limit to a timeout and uses the
user-specified expression timeout value for this. The main motivation is
to allow users on targets where we can't use the JIT to run more
complicated expressions if they really want to (which they can do now by
just increasing the timeout).
The time-based approach also seems much more meaningful than the
arbitrary (and very low) instruction limit. 4096 instructions can be
interpreted in a few microseconds on some setups but might take much
longer if we have a slow connection to the target. I don't think any
user actually cares about the number of instructions that are executed
but only about the time they are willing to wait for a result.
Based off an original patch by Raphael Isemann.

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.

Eliminate boilerplate of having each test manually assign to `mydir` by calling
`compute_mydir` in lldbtest.py.

Summary:
The Scalar class claims to follow the C type conversion rules. This is
true for the Promote function, but it is not true for the implicit
conversions done in the getter methods.
These functions had a subtle bug: when extending the type, they used the
signedness of the *target* type in order to determine whether to do
sign-extension or zero-extension. This is not how things work in C,
which uses the signedness of the *source* type. I.e., C does
(sign-)extension before it does signed->unsigned conversion, and not the
other way around.
This means that: (unsigned long)(int)-1
is equal to (unsigned long)0xffffffffffffffff
and not (unsigned long)0x00000000ffffffff
Unsurprisingly, we have accumulated code which depended on this
inconsistent behavior. It mainly manifested itself as code calling
"ULongLong/SLongLong" as a way to get the value of the Scalar object in
a primitive type that is "large enough". Previously, the ULongLong
conversion did not do sign-extension, but now it does.
This patch makes the Scalar getters consistent with the declared
semantics, and fixes the couple of call sites that were using it
incorrectly.

Summary: Moves lldbsuite tests to lldb/test/API.
This is a largely mechanical change, moved with the following steps:
```
rm lldb/test/API/testcases
mkdir -p lldb/test/API/{test_runner/test,tools/lldb-{server,vscode}}
mv lldb/packages/Python/lldbsuite/test/test_runner/test lldb/test/API/test_runner
for d in $(find lldb/packages/Python/lldbsuite/test/* -maxdepth 0 -type d | egrep -v "make|plugins|test_runner|tools"); do mv $d lldb/test/API; done
for d in $(find lldb/packages/Python/lldbsuite/test/tools/lldb-vscode -maxdepth 1 -mindepth 1 | grep -v ".py"); do mv $d lldb/test/API/tools/lldb-vscode; done
for d in $(find lldb/packages/Python/lldbsuite/test/tools/lldb-server -maxdepth 1 -mindepth 1 | egrep -v "gdbremote_testcase.py|lldbgdbserverutils.py|socket_packet_pump.py"); do mv $d lldb/test/API/tools/lldb-server; done
```
lldb/packages/Python/lldbsuite/__init__.py and lldb/test/API/lit.cfg.py were also updated with the new directory structure.
