VS Code issues relating to new terminal activation feature

[karrtikr]

This is to track outstanding VS Code bugs so terminal activation feature can stabilize:

• .zshrc is overriding the environment variable set by shell integration on macOS vscode#205102
• Prepending using shell integration does not work for zsh, even when shell integration is activated vscode#205133
• Expose API whether shell integration is working or not vscode#205058
• onDidExecuteTerminalCommand does not fire events for hidden terminal vscode#199611
• Environment collection should not be applied on hidden terminals (non-windows) vscode#197187
  • Provide a way to exempt a terminal from applying any env collections vscode#194819
    • This is not needed if #197187 is solved
  • Resolve Provide a way to exempt a terminal from applying any env collections vscode#194819 (comment)
  • Resolve Environment collection should not be applied on hidden terminals (non-windows) vscode#197187 (comment)
• onDidWriteTerminalData event does not contain shell integration sequences for hidden terminals vscode#204616
• Prepending using shell integration does not work for fish when using starship prompt vscode#208465
• Ensure we use correct workspace folder for remote terminals vscode#180486
  • Multiroot workspaces for remote scenarios does not work currently because of this
• Expose shell integration command knowledge to extensions vscode#145234
• Explore terminal buffer API vscode#207504
  • We would need this to get command output, if microsoft/vscode#145234 doesn't cover it.
• Shell integration isn't enabled for Debug terminals vscode#204694
• Shell integration isn't enabled for Task terminals vscode#205177
• Environment collection replace API strips equals sign at the end vscode#197603

Our follow up action items based on that:

• Adopt to using VS Code API to access terminal output #22128
• If automatic shell integration is failing to activate environment, recommend users to do manual installation #23113
• Enable experiment for multiroot remote scenarios:

  vscode-python/src/client/common/experiments/helpers.ts

  Lines 12 to 17 in 0438813

  	export function inTerminalEnvVarExperiment(experimentService: IExperimentService): boolean {
  	if (!isTestExecution() && env.remoteName && workspace.workspaceFolders && workspace.workspaceFolders.length > 1) {
  	// TODO: Remove this if statement once https://github.com/microsoft/vscode/issues/180486 is fixed.
  	traceInfo('Not enabling terminal env var experiment in multiroot remote workspaces');
  	return false;
  	}

Issue to keep in mind:
PREPEND: #21906
