This patch will gather debug info & breakpoint info from the statistics dump (from `(SBTarget.GetStatistics())` func) and send to DAP in terminated event.

The statistics content can be huge (especially the `modules`) and dumping in full JSON can create delay in the IDE's debugging UI. (For more details, please read: https://github.com/llvm/llvm-project/commit/7bbd0fba986c241162b77b7e424ad82bc7e17b41 ). Hence, we will filter out large contents before returning it in terminated event.

It will keep all the metadata fields (those starts with "total"). For large contents, it uses the opt-out strategy. Currently it only removes the "modules" field. This way every time a new top-level field being added, we will be able to capture them from DAP log without changing lldb-vscode.

The DAP terminated event should look like
```
{
  "event":"terminated",
  "seq":0,
  "statistics": {
    "memory": <JSON string>
    "targets": <JSON string>, // it's a JSON array, breakpoints info included in each target
    <metadata_key: value> // pairs
  },
  "type":"event"
}
```

All the info above will be append to statistics field in the terminated event

Test Plan

Debugged a simple hello world program from VSCode. Exit debug session in two ways: 1) run to program exit; 2) user initiated debug session end (quit debugging before program exit).
Check DAP log and see both debug sessions have statistics returned in terminated event.

Here's an example when debugging the test program:

```

Currently, the API for a model's custom value comparison returns a
boolean. Therefore, models cannot distinguish between situations where the
values are recognized by the model and different and those where the values are
just not recognized.  This patch changes the return value to a tri-valued enum,
allowing models to express "don't know".

This patch is essentially a NFC -- no practical differences result from this
change in this patch. But, it prepares for future patches (particularly,
upcoming patches for widening) which will take advantage of the new flexibility.

For an exception crashlog, the thread backtraces aren't usually very helpful
and instead, developpers look at the "Application Specific Backtrace" that
was generated by `objc_exception_throw`.

LLDB could already parse and symbolicate these Application Specific Backtraces
for regular textual-based crashlog, so this patch adds support to parse them
in JSON crashlogs, and materialize them a HistoryThread extending the
crashed ScriptedThread.

This patch also includes the Application Specific Information messages
as part of the process extended crash information log. To do so, the
ScriptedProcess Python interface has a new GetMetadata method that
returns an arbitrary dictionary with data related to the process.

A previous patch introduced a common function used to extract offloading
binaries from an image. Therefore we no longer need to duplicate the
functionality in the `llvm-objdump` implementation. Functionally, this
removes the old warning behaviour when given malformed input. This has
been changed to a hard error, which is effectively the same.

This required a slight tweak in the linker wrapper to filter out the
user passing shared objects directly.

Before this patch:
- For `r = or op0, op1`, `tryBitfieldInsertOpFromOr` combines it to BFI when
  1) one of the two operands is bit-field-positioning or bit-field-extraction op; and
  2) bits from the two operands don't overlap

After this patch:
- Right before OR is combined to BFI, evaluates if ORR with left-shifted operand is better.

A motivating example (https://godbolt.org/z/rnMrzs5vn, which is added as a test case in `test_orr_not_bfi` in `CodeGen/AArch64/bitfield-insert.ll`)

ConstantInt::getTrue/getFalse can materialize scalable vectors with all

After submitting the DataLayout fix, some tests fail when they didn't
before. This has to do with the target essentially being ignored when
these tests were run earlier, as the --target x86-unknown-linux-gnu
only has to be correctly formed to be accepted.

Now the target triple is actually being used to get the targetmachine
earlier - before MLIR is generated - so the test that has a valid target
but not available on the platform fails.

Fix is to require x86 registered target when running those tests.
