Bug Summary and Steps to Reproduce

Bug Summary:

Issuing the build command (Ctrl+B) may sometimes cause VSCode to spend 5-10 seconds "Fetching Build Tasks..." (in status bar) before showing the build tasks menu. I've narrowed down the culprit to the CppTools extension and its C/C++ task provider that suggests a task depending on the file type, aka "detected tasks" in the build menu. I was able to fix this issue by changing the "Task: Auto Detect" setting to "off".

Steps to reproduce:

1. Open a workspace/folder with a C/C++ file.
2. Press Ctrl+B and wait for the menu to show.
3. If menu shows immediately, press escape.
4. Repeat steps 2-3 until you see "Fetching Build Tasks..." in the status bar.

Expected behavior:
There shouldn't be any wait for the build tasks menu to show, especially after its already been shown once before. It should be instantaneous.

Start by reproducing the delay with Ctrl+B in a workspace containing a C/C++ file, then inspect the CppTools extension's C/C++ task provider and its detected-task behavior. Compare task fetching with Task: Auto Detect enabled and disabled. Done means the build tasks menu appears without the reported 5–10 second wait while detected tasks continue to work.
