LDC 1.41.0

[kinke]

Glad to announce LDC 1.41. Major changes:

* Based on D 2.111.0+.
* Support for LLVM 20; the prebuilt packages use v20.1.5.
* macOS: Fix programs crashing on startup on macOS v15.4.
* Keep frame pointers by default with `-O` for some targets, 
analogous to clang. This fixes druntime backtraces with optimized 
code (incl. prebuilt druntime/Phobos).
* The prebuilt (non-musl) Linux packages are now generated on 
Ubuntu 22.04; the minimum glibc version has accordingly been 
raised from v2.31 to v2.35.
* Reworked integration of the LLVM compiler-rt libraries. Package 
maintainers may want to see 
[docs/compiler_rt.md](https://github.com/ldc-developers/ldc/blob/master/docs/compiler_rt.md).
