feat: add grind +locals to include local definitions (#11946) 
This PR adds a `+locals` configuration option to the `grind` tactic that
automatically adds all definitions from the current file as e-match
theorems. This provides a convenient alternative to manually adding
`[local grind]` attributes to each definition. In the form `grind?
+locals`, it is also helpful for discovering which local declarations it
may be useful to add `[local grind]` attributes to.

Example usage:
```lean
def foo (n : Nat) : Nat := n + 1

-- Without +locals, grind doesn't know about foo
example (n : Nat) : foo n = n + 1 := by grind  -- fails

-- With +locals, grind can use the equation
example (n : Nat) : foo n = n + 1 := by grind +locals  -- succeeds
```

Instance definitions and internal details are filtered out.
