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.

Add suport for MASK style watchpoints on AArch64 in debugserver
on Darwin systems, for watching power-of-2 sized memory ranges.
More work needed in lldb before this can be exposed to the user
(because they will often try watching memory ranges that are not
exactly power-of-2 in size/alignment) but this is the first part
of adding that capability.

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.

Skip all watchpoint hit-count/ignore-count tests for multithreaded
API tests for now on arm64 Darwin.
On AArch64, insns that trigger a WP are rolled back and we are
notified. lldb needs to disable the WP, insn step, re-enable it,
then report it to the user. lldb only does this full step action
for the "selected thread", and so when a program stops with
multiple threads hitting a stop reason, some of them watchpoints,
any non-selected-thread will not be completed in this way. But
all threads with the initial watchpoint exception will have their
hit-count/ignore-counts updated. When we resume execution, the
other threads sitting at the instruction will again execute &
trigger the WP exceptoin again, repeating until we've gone through
all of the threads.
This bug is being tracked in llvm.org/pr49433 and inside apple
in rdar://93863107
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.

Make category-specifying files visible. There is really no good reason
to keep them hidden, and having them visible increases the chances
that someone will actually spot them.

Summary:
Around a third of our test sources have LLVM license headers. This patch removes those headers from all test
sources and also fixes any tests that depended on the length of the license header.
The reasons for this are:
* A few tests verify line numbers and will start failing if the number of lines in the LLVM license header changes. Once I landed my patch for valid SourceLocations in debug info we will probably have even more tests that verify line numbers.
* No other LLVM project is putting license headers in its test files to my knowledge.
* They make the test sources much more verbose than they have to be. Several tests have longer license headers than the actual test source.
For the record, the following tests had their line numbers changed to pass with the removal of the license header:
lldb-api :: functionalities/breakpoint/breakpoint_by_line_and_column/TestBreakpointByLineAndColumn.py
lldb-shell :: Reproducer/TestGDBRemoteRepro.test
lldb-shell :: Reproducer/TestMultipleTargets.test
lldb-shell :: Reproducer/TestReuseDirectory.test
lldb-shell :: ExecControl/StopHook/stop-hook-threads.test
lldb-shell :: ExecControl/StopHook/stop-hook.test
lldb-api :: lang/objc/exceptions/TestObjCExceptions.py

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.
