[Bug 2052985] Re: [SRU] Upgrade Rust to 1.76.0

[Zixing Liu]

** Description changed:

+ [ Impact ]
+ 
+ * Due to blocking archive work in the 24.04 cycle, Rust 1.76 was not uploaded in time. However, web browsers and kernels may need a Rust version that is newer than 1.75 in the near future.
+ * Users anticipate a newer Rust release in 24.04, as the version was released two months before Noble's release.
+ 
+ [ Test Plan ]
+ 
+ * A Rust ecosystem rebuild was done in
+ https://launchpad.net/~liushuyu-011/+archive/ubuntu/rust-
+ updates-1.76-wrb-2/+packages to ensure compatibility.
+ 
+ [ Where problems could occur ]
+ 
+ * Rust libraries/applications using Rust internal interfaces not part of the Rust standard library public API will fail to build.
+ * Rust libraries/applications exploiting previous Rust soundness checking deficiencies will fail to build.
+ * Rust libraries/applications using nightly features may fail to build.
+ 
+ [ Other Info ]
+ 
+ * Upstream release note:
+ -----------------------------------------------------------------------------
  Upgrade Rust to 1.76.0
  
  Notable changes in 1.76:
  
  * `char` and `u32` now have the same ABI size
  * `std::any::type_name_of_val` is now stable and can be used to print out the type name
