feat: add bitwise operations to reduceNat? and kernel (#3134) 
This adds bitwise operations to reduceNat? and the kernel. It
incorporates some basic test cases to validate the correct operations
are associated.

06e057758e chore: Remove unused variables from kernel 
when I build lean locally, I get a nice and warning-free build
experience with the exception of these two unused variables. They can
probably go?

This is the first step to make `mkForallFVars` and `mkLambdaFVars`
more general.

db38bc4043 fix: missing check at infer_proj 
We should not allow `h.1` if `h` is a proposition and the result is
not. The recursor for `h`'s type can only eliminate into `Prop`.

f0b502aca6 fix: increase the number of heartbeats at Expr.eqv 
On issue #906, `simp` spends a lot of time checking the cache. This
process is time consuming and doesn't allocate memory. Before this
commit, it would take a long time to get the "maximum number of
heartbeats" error message on the example included in this issue.

Closes #906

2d113e83f9 feat: eta struct support for unit-like datatypes

definitionally equal by `etaStruct`.
