chore: Move basic ordered field lemmas (#11503)

These lemmas are needed to define the semifield structure on NNRat, hence I am repurposing Algebra.Order.Field.Defs from avoiding a timeout (which I believe was solved long ago) to avoiding to import random stuff in the definition of the semifield structure on NNRat (although this PR doesn't actually reduce imports there, it will be in a later PR).

Reduce the diff of #11203

chore: banish Type _ and Sort _ (#6499)

We remove all possible occurences of Type _ and Sort _ in favor of Type* and Sort*.

This has nice performance benefits.

chore: reenable eta, bump to nightly 2023-05-16 (#3414)

Now that leanprover/lean4#2210 has been merged, this PR:

removes all the set_option synthInstance.etaExperiment true commands (and some etaExperiment% term elaborators)
removes many but not quite all set_option maxHeartbeats commands
makes various other changes required to cope with leanprover/lean4#2210.
