[lldb] Add SB API to make a breakpoint a hardware breakpoint (#146602)

This adds SBBreakpoint::SetIsHardware, allowing clients to mark an
existing breakpoint as a hardware breakpoint purely through the API.
This is safe to do after creation, as the hardware/software distinction
doesn't affect how breakpoint locations are selected.

In some cases (e.g. when writing a trap instruction would alter program
behavior), it's important to use hardware breakpoints. Ideally, we’d
extend the various `Create` methods to support this, but given their
number, this patch limits the scope to the post-creation API. As a
workaround, users can also rely on target.require-hardware-breakpoint or
use the `breakpoint set` command.
