This patch adds the following methods:
* `GetType()`
* `GetWatchValueKind()`
* `GetWatchSpec()`
* `IsWatchingReads()`
* `IsWatchingWrites()`
These mostly expose methods that `lldb_private::Watchpoint` already
had. Tests are included that exercise these new methods.
The motivation for exposing these are as follows:
* `GetType()` - With this information and the address from a watchpoint
it is now possible to construct an SBValue from an SBWatchpoint.
Previously this wasn't possible. The included test case illustrates
doing this.
* `GetWatchValueKind()` - This allows the caller to determine whether the
watchpoint is a variable watchpoint or an expression watchpoint. A new
enum (`WatchpointValueKind`) has been introduced to represent the
return values. Unfortunately the name `WatchpointKind` was already
taken.
* `GetWatchSpec()` - This allows (at least for variable watchpoints)
to use a sensible name for SBValues created from an SBWatchpoint.
* `IsWatchingReads()` - This allow checking if a watchpoint is
monitoring read accesses.
* `IsWatchingWRites()` - This allow checking if a watchpoint is
monitoring write accesses.

Instead of maintaining separate swig interface files, we can use the API
headers directly. They implement the exact same C++ APIs and we can
conditionally include the python extensions as needed. To remove the
swig extensions from the API headers when building the LLDB
framework, we can use the unifdef tool when it is available. Otherwise
we just copy them as-is.
