[lldb-dap] Added "port" property to vscode "attach" command. (#91570)

Adding a "port" property to the VsCode "attach" command likely extends
the functionality of the debugger configuration to allow attaching to a
process using PID or PORT number.
Currently, the "Attach" configuration lets the user specify a pid. We
tell the user to use the attachCommands property to run "gdb-remote ".
Followed the below conditions for "attach" command with "port" and "pid"
We should add a "port" property. If port is specified and pid is not,
use that port to attach. If both port and pid are specified, return an
error saying that the user can't specify both pid and port.

Ex - launch.json
{
"version": "0.2.0",
"configurations": [
{
"name": "lldb-dap Debug",
"type": "lldb-dap",
"request": "attach",
"gdb-remote-port":1234,
"program": "${workspaceFolder}/a.out",
"args": [],
"stopOnEntry": false,
"cwd": "${workspaceFolder}",
"env": [],

}
]
}

[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.

These two functions are doing the same thing, only one of them is

later. The first one is better as in case of errors, the backtrace will
point straight to the place that caused them.

Modify the first method to avoid duplication, and ten standardize on it.

[lldb/test] Test lldb-server named pipe functionality on windows

lldb-server can use a named pipe to communicate the port number it is
listening on. This windows bits of this are already implemented, but we
did not have a test for that, most likely because python does not have
native pipe functionality.

This patch implements the windows bits necessary to test this. I'm using
the ctypes package to call the native APIs directly to avoid a
dependency to non-standard python packages. This introduces some amount
of boilerplate, but our named pipe use case is fairly limited, so we
should not end up needing to wrap large chunks of windows APIs.

Surprisingly to changes to lldb-server were needed to make the test
pass.

[lldb/test] Automatically skip remote lldb-server tests when applicable

The tests don't work with remote debugservers. This isn't a problem with
any particular test, but the test infrastructure itself, which is why
each of these tests has a @skipIfDarwinEmbedded decorator.

This patch replaces that with a central category-based solution. It also
moves the ad-hoc windows skipping mechanism there too.

[lldb/test] Reduce boilerplate in lldb-server tests

Nearly all of our lldb-server tests have two flavours (lldb-server and
debugserver). Each of them is tagged with an appropriate decorator, and
each of them starts with a call to a matching "init" method. The init
calls are mandatory, and it's not possible to meaningfully combine them
with a different decorator.

This patch leverages the existing decorators to also tag the tests with
the appropriate debug server tag, similar to how we do with debug info
flavours. This allows us to make the "init" calls from inside the common
setUp method.

[lldb] Use reverse connection method for lldb-server tests

[lldb] Use reverse connection method for lldb-server tests

This fixes an flakyness is all gdb-remote tests. These tests have been
(mildly) flaky since we started using "localhost" instead of 127.0.0.1
in the test suite. The reason is that lldb-server needs to create two
sockets (v4 and v6) to listen for localhost connections. The algorithm
it uses first tries to select a random port (bind(localhost:0)) for the
first address, and then bind the same port for the second one.

The creating of the second socket can fail as there's no guarantee that
port will be available -- it seems that the (linux) kernel tries to
choose an unused port for the first socket (I've had to create thousands
of sockets to reproduce this reliably), but this can apparantly fail
when the system is under load (and our test suite creates a _lot_ of
sockets).

The socket creationg operation is considered successful if it creates at
least one socket is created, but the test harness has no way of knowing
which one it is, so it can end up connecting to the wrong address.

I'm not aware of a way to atomically create two sockets bound to the
same port. One way to fix this would be to make lldb-server report the
address is it listening on instead of just the port. However, this would
be a breaking change and it's not clear to me that's worth it (the
algorithm works pretty well under normal circumstances).

Instead, this patch sidesteps that problem by using "reverse"
connections. This way, the test harness is responsible for creating the
listening socket so it can pass the address that it has managed to open.
It also results in much simpler code overall.

To preserve test coverage for the named pipe method, I've moved the
relevant code to a dedicated test. To avoid original problem, this test
passes raw addresses (as obtained by getaddrinfo(localhost)) instead of
"localhost".
