**Describe the bug** The `AppImage` doesn't launch from within a Linux console, both in a remote SSH console and on Linux desktop. ``` $ wget https://opencl.gpuinfo.org/downloads/openclcapsviewer_1.00_linux64_x11.AppImage $ ./openclcapsviewer_1.00_linux64_x11.AppImage qt.qpa.plugin: Could...

__opencl_c_integer_dot_product_input_4x8bit / __opencl_c_integer_dot_product_input_4x8bit_packed feature macros are always enabled, even on unsupported devices

[`isDotIntegerProductExtensionSupported()` always returns true](https://github.com/intel/compute-runtime/blob/master/shared/source/helpers/compiler_product_helper_tgllp_and_later.inl#L12-L14), which is incorrect. It leads to the [`__opencl_c_integer_dot_product_input_4x8bit` / `__opencl_c_integer_dot_product_input_4x8bit_packed` feature macros always being present](https://github.com/intel/compute-runtime/blob/master/shared/source/compiler_interface/oclc_extensions.cpp#L111-L117), even on unsupported devices. This means: If any OpenCL application implements...
