refactor(library): keep only basic nat theorems
...
All theorems are proved without using the tactic framework.
Thus, we can define `fin/uint32/uint64` types and their operations
before we define the tactic framework.

refactor(library/init/meta): remove tactic_state.mk_empty
...
The tactic_state object will contain a name_generator for creating fresh
names. `tactic_state.mk_empty` is bad because it does not have sufficient
information to create this name_generator.
Moreover `tactic_state.mk_empty` was only being used to convert
`tactic A` into a `parser A`.
We implement this primitive now in C++. In C++, we will be able
to use the parser name generator to initialize a fresh `tactic_state`.

fix(library/init/meta): mk_fresh_name should not be used to create user facing names
...
The tactic `mk_fresh_name` is used to create internal unique ids.
We should not use them to create (temporary) user facing
names. Reasons:
1- They are "cryptic".
2- They are not very stable. Minor changes in Lean may change the
value returned and may break proofs that rely on these fresh names.

feat(library/tactic/simp_tactic): improve mk_simp_attr
...
- An new simp attribute may depend on other existing attributes
- Add `[norm]` simp attribute. It is an extension of the default `[simp]` attribute.
It should be used to add extra rules for normalizing goals.
These extra rules are used to produce normal forms and/or reduce the
number of constants used in a goal. Here is an example coming from a
discussion with @kha. When working with monads, we may want to
eliminate `<$>` by using the lemma `f <$> x = x >>= pure ∘ f`.
This lemma is in the `[norm]` simp set, but it is not in `[simp]`

This command is not just a cosmetic feature.
We need it to defined `id_rhs` before the tactic framework is defined.
We want `id_rhs` to be used in all definitions generated by the equation
compiler. Right now, it is only used in definitions defined after the
tactic framework.
