This patch is similar in spirit to https://reviews.llvm.org/D84480,
but does the maccatalyst/macosx disambiguation. I also took the
opportunity to factor out the gdb-remote packet log scanning used by
several testcases into lldbutil functions.

Yifan Shen e7af98680a [lldb-vscode ]Add Syntax Highlighting to Disassembly View
When lldb cannot find source file thus IDE renders a disassembly view, add syntax highlighting for constants, registers and final line comments for better debugging experience.
The original plain disassembly view looks like:
{F12401687}
An ideal view is like the screenshot attached.
{F12401515}

In this diff, the mimeType is a kind of media type for formatting the content in the response to a source request. Elements in the disassembly view, like constants, registers and final line comments are colored for highlighting.
A built-in support in the VSCode IDE for syntax highlighting will identify the which mimeType to apply and render the disassembly view as expected.

Jason Molenda abf546dd4f debguserver's type sniffer to only treat .app things that end in .app
On an iOS device, if debugserver is left to figure out how to launch
the binary provided, it looks at the filename to see if it contains
".app" and asks FrontBoard to launch it.  However, if this is actually
a command line app with the characters ".app" in the name, it would
end up trying to launch that via the FrontBoard calls even though it
needed to be launched via posix_spawn.  For instance, a command line
program called com.application.tester.

Jim suggested this patch where we only send binaries that end in ".app"
to FrontBoard.

Often debugsever is invoked with a --launch command line argument to
specify the launch method, and none of this code is hit in that
instance.

Walter Erquinigo 74ab1da028 Redo of Add terminateCommands to lldb-vscode protocol
Summary:
This redoes https://reviews.llvm.org/D79726 and fixes two things.
- The logic that determines whether to automatically disconnect during the tear down is not very dumb compared to the original implementation. Each test will determine whether to do that or not.
- The terminate commands and terminate event were being sent after the disconnect response was sent to the IDE. That was not good, as VSCode stops the debug session as soon as it receives a disconnect response. Now, the terminate event and terminateEvents are being executed before the disconnect response is sent. This ensures that any connection between the IDE and lldb-vscode is alive while the terminate commands are executed. Besides, it also allows displaying the output of the terminate commands on the debug console, as it's still alive.

Walter Erquinigo 0a9e7d0b6b [vscode] set default values for terminateDebuggee for the disconnect request
Summary:
Recently I've noticed that VSCode sometimes doesn't send the terminateDebuggee flag within the disconnectRequest,
even though lldb-vscode sets the terminateDebuggee capability correctly.
This has been causing that inferiors don't die after the debug session ends, and many users have reported issues because of this.

An easy way to mitigate this is to set better default values for the terminateDebuggee field in the disconnect request.
I'm assuming that for a launch request, the default will be true, and for attach it'll be false.

Raphael Isemann 74a51753a6 [lldb] Make order of completions for expressions deterministic and sorted by Clang's priority values.
Summary:

It turns out that the order in which we provide completions for expressions is
nondeterministic. This leads to confusing user experience and also breaks the
reproducer tests (as two LLDB tests can go out of sync due to the
non-determinism in the completion lists)

The reason for the non-determinism is that the CompletionConsumer informs us
about decls in the order in which it finds declarations in the lookup store of
the DeclContexts it visits (mainly this snippet in SemaLookup.cpp):

``` lang=c++
    // Enumerate all of the results in this context.
    for (DeclContextLookupResult R :
         Load ? Ctx->lookups()
              : Ctx->noload_lookups(/*PreserveInternalState=*/false)) {
       [...]
```

This storage of the lookup is sorted by pointer values (see the hash of
`DeclarationName`) and can therefore be non-deterministic. The LLDB code
completion consumer that receives these calls originally expected that the order
of declarations is defined by Clang, but it seems the API expects the client to
provide an order to the completions.

This patch fixes the issue as follows:

* We sort the completions we get from Clang alphabetically and also by the
priority value we get from Clang (with priority value sorting having precedence
over the alphabetical sorting)

* We make all the functions/variables that touch a completion before the sorting
const-qualified. The idea is that this should prevent that we never have
observable side-effect from touching these declarations in a non-deterministic
order (e.g., we don't try to complete the type by accident).

This way we behave like the other parts of Clang which also sort the results by
some deterministic value (usually the name or something computed from a name,
e.g., edit distance to a given string).

We most likely also need to fix the Clang code to make the loop I listed above
deterministic to prevent these issues in the future (tracked in rdar://63442513
). This wouldn't replace the functionality provided in this patch though as we
would still need the priority and overall alphabetical sorting.

Note: I had to increase the lldb-vscode completion limit to 100 as the tests
look for strings that aren't in the first 50 results anymore due to variable
names starting with letters like 'v' (which are now always shown much further
down in the list due to the alphabetical sorting).
