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.

This patch adds the following methods:

* `GetType()`
* `GetWatchValueKind()`
* `GetWatchSpec()`
* `IsWatchingReads()`
* `IsWatchingWrites()`

These mostly expose methods that `lldb_private::Watchpoint` already
had. Tests are included that exercise these new methods.

The motivation for exposing these are as follows:

* `GetType()` - With this information and the address from a watchpoint
  it is now possible to construct an SBValue from an SBWatchpoint.
  Previously this wasn't possible. The included test case illustrates
  doing this.
* `GetWatchValueKind()` - This allows the caller to determine whether the
  watchpoint is a variable watchpoint or an expression watchpoint. A new
  enum (`WatchpointValueKind`) has been introduced to represent the
  return values. Unfortunately the name `WatchpointKind` was already
  taken.
* `GetWatchSpec()` - This allows (at least for variable watchpoints)
  to use a sensible name for SBValues created from an SBWatchpoint.
* `IsWatchingReads()` - This allow checking if a watchpoint is
  monitoring read accesses.
* `IsWatchingWRites()` - This allow checking if a watchpoint is
  monitoring write accesses.

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

Follow to D127355, converting more `assertEquals` to `assertState`.

This tests have recently become flaky (flakier?) causing occasional failures in the windows lldb buildbot

There is a .categories file in the python_api directory that makes all nested tests
belong to the category "pyapi". The decorator is unnecessary for these tests.

Convert `assertTrue(a == b)` to `assertEqual(a, b)` to produce better failure messages.

These were mostly done via regex search & replace, with some manual fixes.

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.
