Auto merge of #84420 - workingjubilee:microvec, r=Mark-Simulacrum

Use arrayvec 0.7, drop smallvec 0.6

With the arrival of min const generics, many alt-vec libraries have
updated to use it in some way and arrayvec is no exception. Use the
latest with minor refactoring.

Also, rustc_workspace_hack is the only user of smallvec 0.6 in the
entire tree, so drop it.
