This patch removes all of the Set.* methods from Status.

This cleanup is part of a series of patches that make it harder use the
anti-pattern of keeping a long-lives Status object around and updating
it while dropping any errors it contains on the floor.

This patch is largely NFC, the more interesting next steps this enables
is to:
1. remove Status.Clear()
2. assert that Status::operator=() never overwrites an error
3. remove Status::operator=()

Note that step (2) will bring 90% of the benefits for users, and step
(3) will dramatically clean up the error handling code in various
places. In the end my goal is to convert all APIs that are of the form

`    ResultTy DoFoo(Status& error)
`
to

`    llvm::Expected<ResultTy> DoFoo()
`
How to read this patch?

The interesting changes are in Status.h and Status.cpp, all other
changes are mostly

` perl -pi -e 's/\.SetErrorString/ = Status::FromErrorString/g' $(git
grep -l SetErrorString lldb/source)
`
plus the occasional manual cleanup.

This patch loosen the parsing requirement to allow parsing not only
JSON dictionaries but also valid JSON type (integer, float, string,
bool, array, null).

This patch adds the ability to pass native types from the script
interpreter to methods that use a {SB,}StructuredData argument.

To do so, this patch changes the `ScriptedObject` struture that holds
the pointer to the script object as well as the originating script
interpreter language. It also exposes that to the SB API via a new class
called `SBScriptObject`.

This structure allows the debugger to parse the script object and
convert it to a StructuredData object. If the type is not compatible
with the StructuredData types, we will store its pointer in a
`StructuredData::Generic` object.

This patch also adds some SWIG typemaps that checks the input argument to
ensure it's either an SBStructuredData object, in which case it just
passes it throught, or a python object that is NOT another SB type, to
provide some guardrails for the user.

This uses some friend class trickery to avoid some unneeded temporary
std::string allocations.

This patch refactors the `StructuredData::Integer` class to make it
templated, makes it private and adds 2 public specialization for both
`int64_t` & `uint64_t` with a public type aliases, respectively
`SignedInteger` & `UnsignedInteger`.

It adds new getter for signed and unsigned interger values to the
`StructuredData::Object` base class and changes the implementation of
`StructuredData::Array::GetItemAtIndexAsInteger` and
`StructuredData::Dictionary::GetValueForKeyAsInteger` to support signed
and unsigned integers.

This patch also adds 2 new `Get{Signed,Unsigned}IntegerValue` to the
`SBStructuredData` class and marks `GetIntegerValue` as deprecated.

Finally, this patch audits all the caller of `StructuredData::Integer`
or `StructuredData::GetIntegerValue` to use the proper type as well the
various tests that uses `SBStructuredData.GetIntegerValue`.

Instead of taking a `const std::string &` we can take an
`llvm::StringRef`. The motivation for this change is that many of the
callers of `ParseJSON` end up creating a temporary `std::string` from an existing
`StringRef` or `const char *` in order to satisfy the API. There's no
reason we need to do this.

Remove the last remaining references to the reproducers from the
instrumentation. This patch renames the relevant files and macros.
