LLDB Adapter leaks breakpoints

[UvuvDev]

Version and Platform (required):

• Binary Ninja Version: 6.1.10613
• OS: MacOS
• OS Version: 27
• CPU Architecture: M3 Pro
• Local or Remote Debugging: Local

Bug Description:
If you set a breakpoint at an address twice, LLDB's original breakpoint never gets freed.

Steps To Reproduce:

1. Open a binary and launch the debugger
2. Set a breakpoint with the API twice on the same address
3. Free the breakpoint
4. Observe that it still breaks at the breakpoint.

Expected Behavior:
It should free a breakpoint before setting a new one at the same address, or it should refuse to overwrite the old breakpoint.
