build(deps): bump rust-toolchain from 1.95.0 to 1.97.1

[dependabot]

Bumps rust-toolchain from 1.95.0 to 1.97.1.

Release notes

Sourced from rust-toolchain's releases.

Rust 1.97.1

• rustc: Fix miscompilation in LLVM optimization This backports an LLVM submodule bump to include the LLVM-side fix and a revert of the rustc change that is one known trigger for the bug. The rustc side revert should not be strictly necessary but is done out of abundance of caution.

Rust 1.97.0

Language

• Consider Result<T, Uninhabited> and ControlFlow<Uninhabited, T> to be equivalent to T for must use lint
• Add allow-by-default dead_code_pub_in_binary lint for unused pub items in binary crates
• Stabilize the div32, lam-bh, lamcas, ld-seq-sa and scq target features
• Stabilize cfg(target_has_atomic_primitive_alignment)
• Allow trailing self in imports in more cases

Platform Support

• nvptx64-nvidia-cuda: drop support for old architectures and old ISAs

Refer to Rust's platform support page for more information on Rust's tiered platform support.

Stabilized APIs

• Default for RepeatN
• Copy for ffi::FromBytesUntilNulError
• Send for std::fs::File on UEFI
• <{integer}>::isolate_highest_one
• <{integer}>::isolate_lowest_one
• <{integer}>::highest_one
• <{integer}>::lowest_one
• <{integer}>::bit_width
• NonZero<{integer}>::isolate_highest_one
• NonZero<{integer}>::isolate_lowest_one
• NonZero<{integer}>::highest_one
• NonZero<{integer}>::lowest_one
• NonZero<{integer}>::bit_width

These previously stable APIs are now stable in const contexts:

• char::is_control
