Filter options passed to ResolutionContext, convert to exact type

Summary:
Update the context object passed to metro-resolver and custom resolvers to match the keys typed for metro-resolver and in our docs.

The keys which are no longer exposed are:
- `dirExists`
- `emptyModulePath`
- `mainFields` (will be re-added)
- `moduleCache`
- `platform`
- `projectRoot`

This is a breaking change that is summarised in the next commit.
