[lldb-dap] Enabling instruction breakpoint support to lldb-dap. (llvm#105278)

Added support for "supportsInstructionBreakpoints" capability and now it
this command is triggered when we set instruction breakpoint.
We need this support as part of enabling disassembly view debugging.
Following features should work as part of this feature enablement:

1. Settings breakpoints in disassembly view: Unsetting the breakpoint is
not happening from the disassembly view. Currently we need to unset
breakpoint manually from the breakpoint List. Multiple breakpoints are
getting set for the same $

2. Step over, step into, continue in the disassembly view

.
