When debugging read-only memory we cannot use software breakpoint. We already have support for hardware breakpoints and users can specify them with `-H`. However, there's no option to force LLDB to use hardware breakpoints internally, for example while stepping. This patch adds a setting target.require-hardware-breakpoint that forces LLDB to always use hardware breakpoints. Because hardware breakpoints are a limited resource and can fail to resolve, this patch also extends error handling in thread plans, where breakpoints are used for stepping.
