rust: Upgrade 1.84.1->1.85.0

Rust stable version updated to 1.85.0
https://blog.rust-lang.org/2025/02/20/Rust-1.85.0.html

Some of the major updates:

- Update LIC_FILES_CHKSUM in libstd-rs and rust recipes.
License-Update: Unicode license text is updated to Unicode-3.0 License.
rust-lang/rust@6d2a3e9

- Pass '-Zforce-unstable-if-unmarked' to RUSTFLAGS in libstd-rs.bb
Fix: rust-lang/rust#133857 (comment)

- Downgrade bootstrap cc version causing bootstrap to fail on custom targets. (Backported from v1.85.1)
Fix: rust-lang/rust@e4ca11f

- Explicitly set float ABI for all ARM 32 bits targets.
Fix: rust-lang/rust@a51fefc

- Rust v1.85.0 tarball doesn't ship gcc tree.
Drop "remove_gcc_directory" postfunc which removed it and prevented the bloat.
Fix: rust-lang/rust@13c3f9b

Adapted the patch changes with v1.85.0:
  repro-issue-fix-with-cc-crate-hashmap.patch
  revert-link-std-statically-in-rustc_driver-feature.patch
  rust-oe-selftest.patch
  rv32-cargo-rustix-0.38.40-fix.patch

Dropped patches:
  fix-tidy-check-failure.patch since it's merged with v1.85.0.

+Downgrade bootstrap cc version
+
+In rust v1.85.0, the upgraded cc version causes bootstrap
+to fail on custom targets. Downgrading the cc version fixes
+the error. This commit is merged with v1.85.1 and the patch
+can be dropped when upgraded to it.
