Revert "Make toolchain inspection more robust"
This reverts commit 7c62caa3555d247be569102d8f01b3e7ae362b8a.
Certain toolchain files cannot be read in CMake script mode with CMake
versions >= 3.20.
For example, the vcpkg toolchain file overrides add_executable, and
that fails with CMake 3.20:
CMake Error at D:/dev_tools/vcpkg/scripts/buildsystems/vcpkg.cmake:662 (function):
Built-in flow control command "add_executable" cannot be overridden.
Pick-to: 6.2
Fixes: QTBUG-93627
Change-Id: Ib6e6352dff50b9684dcf81401d138e27e16292c3
