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.

 # Order isomorphism between a linear ordered field and `(-1, 1)`

6cb77a8e

chore: bye-bye, solo bys! (#3825)

This PR puts, with one exception, every single remaining by that lies all by itself on its own line to the previous line, thus matching the current behaviour of start-port.sh. The exception is when the by begins the second or later argument to a tuple or anonymous constructor; see https://github.com/leanprover-community/mathlib4/pull/3825#discussion_r1186702599.

Essentially this is s/\n *by$/ by/g, but with manual editing to satisfy the linter's max-100-char-line requirement. The Python style linter is also modified to catch these "isolated bys".

feat: port field_simp tactic (#1824)

Ports the field_simp tactic and tests from mathlib3.
Adds a new test taken from minif2f (but with rats instead of reals, for simplicity): https://github.com/openai/miniF2F/blob/4e433ff5cadff23f9911a2bb5bbab2d351ce5554/lean/src/valid.lean#L524-L530.
Uses field_simp in two already-ported files, as directed by port notes.
Adds an explicit priority to a few field_simps lemmas. This is necessary to make all of the examples work.
