asdf/uiop version bump to 3.3.6

[Cyrus Harmon]

The attached patch upgrades SBCL's built in ASDF and UIOP to version 3.3.6.

A git repo with the patch applied can also be found here:

https://github.com/slyrus/sbcl/tree/asdf_3_3_6

This builds and run on macOS (m1) and linux. I have not tried windows.

We've gone down this road before. https://bugs.launchpad.net/sbcl/+bug/1823442 makes the case for users choosing to upgrade ASDF on their own, on top of the bundled ASDF.

I intend to remove the use of ASDF to build contribs, so the trade-offs will be different, I think for the better. Google uses https://bazel.build/ to build the contribs, which is a viable competitor to ASDF that previous discussions allude to. But in the SBCL distribution I'd like to avoid using either bazel or ASDf.

and https://bugs.launchpad.net/sbcl/+bug/1826074 says the same thing in different words

[Cyrus Harmon (ch-launchpad)]

So now that the contribs don't build with ASDF can we either update ASDF or remove it?
