Improving iree-dump-module output. (#13614)

FlatBuffer JSON is still available but by default a much more readable
output helps identify section sizes, exported function signatures, and
dependencies/requirements.

Example output:
```
//===--------------------------------------------------------------------------------------------------------------===//
// @module : version 0
//===--------------------------------------------------------------------------------------------------------------===//

Required Types:
  [  0] i32
  [  1] i64
  [  2] !hal.allocator
  [  3] !hal.buffer
  [  4] !hal.buffer_view
  [  5] !hal.command_buffer
  [  6] !hal.descriptor_set_layout
  [  7] !hal.device
  [  8] !hal.executable
  [  9] !hal.fence
  [ 10] !hal.pipeline_layout
  [ 11] !vm.buffer
