lint_fix: various quality of life improvements
This revamps lint_fix to do as much as possible
directly in python, rather than stitching together shell commands.
It also adds a few small features to lint_fix to save time and
confusion:
- Rather than having to specify the `full/math/to/a/module`, one can
just specify the module name: e.g. `framework-minus-apex` instead
of `frameworks/base/framework-minus-apex`
- Add a `--lint-module` argument to specify a custom lint module to
be passed to the lint invocation. This is useful when we want to run
all checks from that module (rather than specifying each one
individually).
- Add a `--print` argument to print the contents of the lint report at
the end. This is useful for invocations that lead to warnings but
not errors.
