[Bug 2125155] [NEW] Rustc 1.83 not available on Noble (SRU tracking issue)

[Petrichor Park]

Public bug reported:

Rustc 1.83 is currently not available in the Noble archives. However, the
QEMU devs would like to be able to run their Rust CI tests on LTS Ubuntu
build servers, as part of their movement to include more and more Rust code.
I confirmed that they would like to access this port as an SRU via IRC
(conversation transcluded at the end).

I have created a port of Rustc 1.83 to Noble, available at 
ppa:petrakat/rust-1.83-merge, version string 1.83.0+dfsg0ubuntu1~bpo2-0ubuntu1.24.04~ppa1.

[ Impact ]

 * Most users will not be impacted by this. It allows developers to run
   Rust CI on more platforms.

 * This upload follows the standard Rustc backport procedure; I downgraded
   libgit2 and vendored LLVM.

[ Test Plan ]

 * To reproduce:
   - Look at pad.lv/u/rustc-1.83
   - It's not available for Noble

[ Where problems could occur ]

 * In the event that there is some disastrous bug, the effects will still be
   quite small on the end user because you have to opt in to using this package.

 * If this SRU is later used to compile other SRU'd packages that use Rust, it
   is possible that bugs in this port cause those packages to fail.

 * QEMU is a reasonably high-profile project, and if errors in this code cause
   large delays or errors in QEMU it is quite possible we will get bad publicity.

 * I believe the risk of such disastrous bugs is very low, as the changes to
   rustc source itself are minimal (one line), and the autopackage tests
   are quite thorough.

[ Other Info ]

 * This port was originally requested as bug #2109898, and the porting process
   was done as bug #2120318.

 * Please excuse the strange version string; it adheres to the standard
   formatting for Rust backports.

 * I have never filed an SRU before so please be patient :)
