Launch the app via open cmd on macOS

[deepak1556]

Currently some users hit an issue where the app launched from command line doesn't have an active dock icon, menu and the window cannot be focused.

Thanks for help from @MarshallOfSound with the debugging we were able to narrow the source of issue. The cli wrapper is a node process which then spawns the actual app https://github.com/microsoft/vscode/blob/master/src/vs/code/node/cli.ts#L331 , this doesn't work well with entitlements. Can read for some background about inherited entitlements #95062 (comment) .

The underlying issue is not known here but we expect some sort of malformed state has been entered by the entitled app. To fix this we can adjust the spawn callsite with a call to macOS open cmd.

@deepak1556 we have to be careful to still support our command line flags. Here is a simple test that fails if we switch to open:

• run alias code='open -b com.microsoft.VSCode "$@"' in terminal
• type code --list-extensions
• it fails

@bpasero the open command is only meant to be used for spawning the final app executable https://github.com/microsoft/vscode/blob/master/src/vs/code/node/cli.ts#L331, it is not meant to replace the cli wrapper which respects those command line arguments.

const child = spawn('open', ['-b', 'com.microsoft.VSCode', '--args', argv], options);

@deepak1556 oh I see!
