Update GSC with Gramine's new SGX Driver Requirements

[anjalirai-intel]

Description of the problem

As part of the Remove support for OOT (out-of-tree) SGX driver commit in the Gramine master branch, the options -Dsgx_driver, -Dsgx_driver_include_path, and -Dsgx_driver_device have been removed. Similar changes should be backported into GSC as well. Currently, workloads are failing during the Meson build with the error Unknown options: "sgx_driver, sgx_driver_include_path".`

Comments from Gramine PR

Since Gramine v1.9, we only support upstream, in-kernel driver and the
``-Dsgx_driver`` option, as well as associated ``-Dsgx_driver_include_path`` and
``-Dsgx_driver_device`` options, are gone.

Steps to reproduce

Expected results

GSC master should be fully compatible with Gramine master and kept up-to-date. Any significant changes made in Gramine that impact GSC should be updated to support Gramine and the new build requirements.

Actual results

Step 9/9 : RUN cd /gramine     && meson setup build/ --prefix="/gramine/meson_build_output"        --buildtype=release        -Ddirect=enabled -Dsgx=enabled                        -Dsgx_driver=upstream -Dsgx_driver_include_path=/gramine/driver             && ninja -C build     && ninja -C build install
