Subject: [PATCH 2/4] [lldb-dap] Added "port" property to vscode "attach"
command.
Adding a "port" property to the VsCode "attach" command likely extends the functionality of the debugger configuratiuon to allow attaching to a process using PID or PORT number.
Currently, the "Attach" configuration lets the user specify a pid. We tell the user to use the attachCommands property to run "gdb-remote <port>".
Followed the below conditions for "attach" command with "port" and "pid"
We should add a "port" property. If port is specified and pid is not, use that port to attach. If both port and pid are specified, return an error saying that the user can't specify both pid and port.
Ex - launch.json
{
"version": "0.2.0",
"configurations": [
{
"name": "lldb-dap Debug",
"type": "lldb-dap",
"request": "attach",
"port":1234,
"program": "${workspaceFolder}/a.out",
"args": [],
"stopOnEntry": false,
"cwd": "${workspaceFolder}",
"env": [],
}
]
}

We should add a "port" property. If port is specified and pid is not, use that port to attach. If both port and pid are specified, return an error saying that the user can't specify both pid and port.
Ex - launch.json
{
"version": "0.2.0",

"program": "${workspaceFolder}/a.out",
"args": [],
"stopOnEntry": false,
"cwd": "${workspaceFolder}",
"env": [],
}
]
}
In this patch we have resolved code formatting issues and fixed "test_by_name" failure.
