Update toolchain to 2023-02-16

[tautschnig]

Description of changes:

Skip over all the nightlies from 2023-02-06 until 2023-02-15 as those ICE when trying to build kani with:

error: internal compiler error: cannot relate constants (Const { ty: fn() -> usize {std::mem::size_of::<[T; N]>}, kind: Value(Branch([])) }, Const { ty: fn() -> usize {std::mem::size_of::<[T; _]>}, kind: Value(Branch([])) }) of different types: fn() -> usize {std::mem::size_of::<[T; N]>} != fn() -> usize {std::mem::size_of::<[T; _]>}

This issue was reported upstream as rust-lang/rust#107898, and fixed in rust-lang/rust#107940, which isn't part of any of the above nightlies.

Doing this multi-day update also requires addressing:

Remove some superfluous type parameters from layout.rs rust-lang/rust#107163
Introduce -Zterminal-urls to use OSC8 for error codes rust-lang/rust#107838
s/eval_usize/eval_target_usize/ for clarity rust-lang/rust#108029
