chore: add/improve npm ignore configs (#328)

Summary:
I noticed that a bunch of test files were being bundled with npm packages.
We encounter also the risk to bundle log and .tgz (npm packged module) files when running npm publish.
This diff attends to this problem by improving/adding an `.npmignore` config to each sub-module.

I've also updated the CHANGELOG.md file and even fixed-up some other things (like adding a missing section for one of our modules).

Pull Request resolved: #328

Test Plan:
Script to generate list of npm package files:

```
function packlist() {
  pushd "packages/$1"
  yarn pack > /dev/null; npx npm-packlist | sort
  popd > /dev/null
}

echo "" > packlist.log
packlist babel-plugin-fbt >> packlist.log
packlist babel-plugin-fbt-runtime >> packlist.log
packlist babel-plugin-standalone >> packlist.log
packlist default-collection-transform >> packlist.log
packlist fb-babel-plugin-utils >> packlist.log
packlist fb-tiger-hash >> packlist.log
packlist fbt >> packlist.log
packlist gulp-rewrite-flowtyped-modules >> packlist.log
packlist gulp-strip-docblock-pragmas >> packlist.log
packlist react-native-fbt >> packlist.log

pastry < packlist.log
```
