[GSoC] Rust: Compiling the alloc crate - Status Report 6

Hi!
This is the sixth and final report on compiling the alloc crate with
GCCRS.

This email serves as the concluding status report for my GSoC project.
At this point, I have addressed all the missing infrastructure required
to support alloc. With my latest 3 pull requests (which are currently
awaiting review), I have significantly advanced the CoerceUnsized
support and successfully implemented this behavior for the Box type.

Additionally, I submitted the alloc testsuite. It is currently
configured to compile the crate up to the name resolution phase, as we
decided it is best to keep it strictly synchronized with the current
capabilities of the core testsuite.

If you are interested in the details, I have prepared a comprehensive
final report here:
https://gccrs.nsvke.com

Moving forward, I plan to stay around and continue contributing to
gccrs as a regular contributor as my time allows. Thank you for taking
the time to read my reports and following along with my progress
throughout this program!

Best regards,
Enes
