Use std-shims to reduce flexible-transcript MSRV to 1.66
...
flexible-transcript already had a shim to support <1.66. This was irrelevant
since flexible-transcript had a MSRV of 1.73. Due to how clunky it was, it has
been removed despite theoretically enabling an even lower MSRV.

Unused and unpublished. This was only added in the FCMP++ branch as a quick fix
for performance reasons. Finding a better API is still a tricky question, but
this API is _bad_.

Expose Once within std-shims, bump spin to 0.9
...
This is technically a semver break due to bumping spin to 0.10, with the types
from spin being directly exposed. Long-term, we should not directly expose spin
but instead have our own types which are thin wrappers around spin (clearly
defining our API and allowing upgrading internals without breaking semver).
