Activation Event * causes ms-vscode.cpptools to load in every directory

[daniel-stoneuk]

I was encountering extremely high (100%) CPU usage from the ms-vscode.cpptools cpptools process and determined that it was due to that extension indexing every single file within my home directory. This would go on continuously, and even after VSCode was closed. I'll be making an issue over there for why the process continued after the VSCode process ended.

Since the Arduino extension is set to activate whenever VSCode starts up, and is dependent on the C++ extension, an empty VSCode window with no open project would cause this issue to occur. For this reason I have had to disable the Arduino extension.

Would it be possible to reduce the scope of the activation events to only run when relevant files are found or commands run?

An update from the linked issue in vscode-cpptools: the high CPU usage was due to a misconfiguration on my machine. However, I believe this would still be a good change to make.

I agree with this change. It takes about half a second to load this extension with vscode-cpptools.
This may seem like a negligible time, but these two extensions are loading the slowest of the all installed extensions...

Fixed by #1481.

This issue has been fixed in the latest release of this extension, which is available in the VS Code extension marketplace.
