Bump rayon from 1.5.3 to 1.7.0

[dependabot]

Bumps rayon from 1.5.3 to 1.7.0.

Changelog

Sourced from rayon's changelog.

Release rayon 1.7.0 / rayon-core 1.11.0 (2023-03-03)

• The minimum supported rustc is now 1.59.
• Added a fallback when threading is unsupported.
• The new ParallelIterator::take_any and skip_any methods work like unordered IndexedParallelIterator::take and skip, counting items in whatever order they are visited in parallel.
• The new ParallelIterator::take_any_while and skip_any_while methods work like unordered Iterator::take_while and skip_while, which previously had no parallel equivalent. The "while" condition may be satisfied from anywhere in the parallel iterator, affecting all future items regardless of position.
• The new yield_now and yield_local functions will cooperatively yield execution to Rayon, either trying to execute pending work from the entire pool or from just the local deques of the current thread, respectively.

Release rayon-core 1.10.2 (2023-01-22)

• Fixed miri-reported UB for SharedReadOnly tags protected by a call.

Release rayon 1.6.1 (2022-12-09)

• Simplified par_bridge to only pull one item at a time from the iterator, without batching. Threads that are waiting for iterator items will now block appropriately rather than spinning CPU. (Thanks @​njaard!)
• Added protection against recursion in par_bridge, so iterators that also invoke rayon will not cause mutex recursion deadlocks.

Release rayon-core 1.10.1 (2022-11-18)

• Fixed a race condition with threads going to sleep while a broadcast starts.

Release rayon 1.6.0 / rayon-core 1.10.0 (2022-11-18)

• The minimum supported rustc is now 1.56.
• The new IndexedParallelIterator::fold_chunks and fold_chunks_with methods work like ParallelIterator::fold and fold_with with fixed-size chunks of items. This may be useful for predictable batching performance, without the allocation overhead of IndexedParallelIterator::chunks.
• New "broadcast" methods run a given function on all threads in the pool. These run at a sort of reduced priority after each thread has exhausted their local work queue, but before they attempt work-stealing from other threads.
  • The global broadcast function and ThreadPool::broadcast method will block until completion, returning a Vec of all return values.
  • The global spawn_broadcast function and methods on ThreadPool, Scope, and ScopeFifo will run detached, without blocking the current thread.
• Panicking methods now use #[track_caller] to report the caller's location.
• Fixed a truncated length in vec::Drain when given an empty range.

@ryoqun , do you mind looking at this version bump? Any concerns?

lgtm

I reviewed rayon's changelog, commit log, actual diff of package contents. saw no concerns. it looks like most of changes are MSRV bump and new additions. there's potential perf impacting change of .par_bridge but it looks like we aren't using it.

Do you understand why the metrics step is consistently failing: https://buildkite.com/solana-labs/metrics-main-status/builds/11#01874f2f-bb61-4b10-af5b-24818dd02727
Would it affect other CI runs on master?

I don't think that job was supposed to run as part of PR CI in the first place: #31000
