Lakshya Singh 33292b5d3e gcc: Fix Compatibility Issue with GCC 13
This commit addresses a compatibility issue introduced by GCC
in version 13 (refer to [1]). The issue is present in both
the Arch base system and the latest version of Fedora.

To resolve this, the commit introduces a Kernel-mimicking approach
through a new `Compiler.hpp` file. In this file, we define various
compiler hacks required to enhance code readability by reducing verbosity.

For more details on the issue, see [1]: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=107134
