eefda18227 [lldb/Plugins] Move SBTarget::GetExtendedCrashInformation to SBProcess
This patch moves the SB API method GetExtendedCrashInformation from
SBTarget to SBProcess since it only makes sense to call this method on a
sane process which might not be the case on a SBTarget object.

It also addresses some feedbacks received after landing the first patch
for the 'crash-info' feature.

d7c403e640 [lldb/Plugins] Add ability to fetch crash information on crashed processes
Currently, in macOS, when a process crashes, lldb halts inside the
implementation disassembly without yielding any useful information.
The only way to get more information is to detach from the process, then wait
for ReportCrash to generate a report, find the report, then see what error
message was included in it. Instead of waiting for this to happen, lldb could
locate the error_string and make it available to the user.

This patch addresses this issue by enabling the user to fetch extended
crash information for crashed processes using `process status --verbose`.

Depending on the platform, this will try to gather different crash information
into an structured data dictionnary. This dictionnary is generic and extensible,
as it contains an array for each different type of crash information.

On Darwin Platforms, lldb will iterate over each of the target's images,
extract their `__crash_info` section and generated a StructuredData::Array
containing, in each entry, the module spec, its UUID, the crash messages
and the abort cause. The array will be inserted into the platform's
`m_extended_crash_info` dictionnary and `FetchExtendedCrashInformation` will
return its JSON representation like this:

```
{
  "crash-info annotations": [
    {
      "abort-cause": 0,
      "image": "/usr/lib/system/libsystem_malloc.dylib",
      "message": "main(76483,0x1000cedc0) malloc: *** error for object 0x1003040a0: pointer being freed was not allocated",
      "message2": "",
      "uuid": "5747D0C9-900D-3306-8D70-1E2EA4B7E821"
    },
    ...
  ],
  ...
}
```

This crash information can also be fetched using the SB API or lldb-rpc protocol
using SBTarget::GetExtendedCrashInformation().

6498aff249 [lldb/Bindings] Move bindings into their own subdirectory
All the code required to generate the language bindings for Python and
Lua lives under scripts, even though the majority of this code aren't
scripts at all, and surrounded by scripts that are totally unrelated.

I've reorganized these files and moved everything related to the
language bindings into a new top-level directory named bindings. This
makes the corresponding files self contained and much more discoverable.
