pyoxidizer: use in-memory resources on non-Windows platforms In-memory resources were disabled for macOS in 7bc1beed, and for all platforms in c900d962. Unfortunately this made it so that we were no longer producing standalone binaries on these platforms, and would have to ship the .py and .pyc files alongside the pyoxidized binary. These changes are no longer necessary after f6b04591, which disabled pep517 and solved the issue we were encountering. Differential Revision: https://phab.mercurial-scm.org/D11734

compat: don't rely on cpython-specific builtins manipulation Pierre Augier signaled on the mailing list that this fails on Pypy and pointed out the correct solution. Differential Revision: https://phab.mercurial-scm.org/D11732

rust-format: update rustfmt version This hasn't been updated in a while, and since we're updating the MSRV to 1.48.0, we might as well do this. Differential Revision: https://phab.mercurial-scm.org/D11733

rust: update the minimum version of Rust Debian Bullseye has just been released, and it carries `rustc 1.48.0`. This actually implies a regression that we can't really do anything about in `rhg`. See https://github.com/rust-lang/rust/issues/88825. In short, closed (or bad) standard file descriptors are reopened silently with no way of telling by the Rust runtime before `main` is executed. This means that closed fds are not forwarded to the subprocess we run in case of fallback. This is a bit sad, but probably not something worth worrying too much about.
