[lldb] Update LLDB DAP documentation. (#172580)
This adds a new page to lldb.llvm.org that includes a user guide for
lldb-dap.
The overall structure for documentation:
* https://lldb.llvm.org/resources/lldbdap.html - represents the user
facing documentation for lldb-dap, a high level overview of lldb-dap and
a place we can point users to for basic usage information.
* https://lldb.llvm.org/resources/lldbdap-contributing.html - represents
the contributing documentation for lldb-dap.
* llvm-project/lldb/tools/lldb-dap/README.md - The lldb-dap VSCode
Extension specific documentation.
This is a first pass at the documentation, I expect to expand on it
further as needed.
