Changes [Distributed._default_worker_pool](https://github.com/JuliaLang/julia/blob/5f5d2040511b42ba74bd7529a0eac9cf817ad496/stdlib/Distributed/src/workerpool.jl#L242) to hold an `AbstractWorkerPool` instead of `WorkerPool`. With this, alternate implementations can be plugged in as the default pool. Helps in cases where a cluster is always meant to use a certain custom pool. Lower level calls can then work without having to pass a custom pool reference with every call.

We generally hit the runtime in pretty specific places when allocations
look funky (because they are missing a typevar bound, so inference is
not too willing to deal with it). Try to throw an error in those cases
before those can get allocated and cause problems later from being
non-concrete objects.

(cherry picked from commit 4ccaa1b)

This release of libblastrampoline contains two new features: ILP64 Accelerate support, and LAPACK_jll support.

(cherry picked from commit 4ced71a)

This changes the behavior of `select_platform()` to resolve ambiguities
using a two-step process.  Previously, we would simply sort the
resultant triplets and return the last one (so as to provide asemi-
arbitrary stability, and also to prefer higher version numbers over
lower version numbers in tags).  However, with the proliferation of tags
(and especially the new `sanitize=memory` tags) we need a way to exclude
these "extra" tags when our `HostPlatform()` does not have them.

This new matching algorithm excludes candidates from matching with the
platform if there are other candidates with fewer total tags.  This
results in a "simplest match first" behavior, which better represents
the intent of tags in the first place.

This is the same as #45765 where
we use `jl_error()` too early to get backtraces, but too late to fail
the supposed guard `if` statement that should prevent us from trying to
take a backtrace.  X-ref: #45847
