rust: Upgrade 1.90.0 -> 1.91.0

https://blog.rust-lang.org/2025/10/30/Rust-1.91.0/

* Recent updates to rustc now require 'target_pointer_width'
  to be specified as an integer.
  Cast it to 'int' in rust target configuration to resolve the
  type consistency error.
  rust-lang/rust#144443

* The "remote-test-server" bin is now generated in stage2-tools-bin dir
  rather than stage1. Update the test suite and recipe accordingly.

* Rebase existing patches with v1.91.0.

* Drop merged patches with rust v1.91.0.
