  [lldb][debugserver] Fix an off-by-one error in watchpoint identification (#134314)

debugserver takes the address of a watchpoint exception and calculates
which watchpoint was responsible for it. There was an off-by-one error
in the range calculation which causes two watchpoints on consecutive
ranges to not correctly identify hits to the second watchpoint. The
result is that lldb wouldn't show the second watchpoint as ever being
hit.
