dev-lang/rust: add 1.86.0_beta20250225
This commit also default-enables the `system-llvm` USE.
We have not had any reported issues with system-llvm
for a long time and upstream Rust do their best to
ensure that any required patches are merged into LLVM
early.
This should flow through into the next stable release
if no issues are encountered, and the p.stable.mask will
be removed.
