Summary: Oftentimes packager stalls for several seconds after requiring a bundle, because it's busy cleaning up old cache files. We shouldn't do that when, for example, we just restarted packager. This changeset stores the micro-timestamp of the last collection so that we don't waste time next time.

Summary:
Note: if this changeset causes some breakage, consider disabling rather than reverting. To disable, the call to `_preprocessPotentialDependencies` in `ResolutionRequest` can be removed.
It's a bit of an experiment. I couldn't see any particular regression caused by this, but I could see net improvement of the global cache performance, as it unlock much, much stronger batching: indeed, instead of discovering dependencies progressively, we synchronously figure out the list of all potential modules of a bundle, and kick-off cache fetching and/or transformations. So when it comes to fetching from the global cache, it'll do less requests, and each requests will ask for considerably more keys at a time.
Potential problem caused by this changeset: if a module's dependencies completely changed, then the first time we try to build the bundle it'll start transforming modules that we probably don't care at all anymore, spending precious CPU time for nothing. I've been thinking about it and I cannot see such a case happening much often. Even if it happens, it should not cause any bug or corruption, it would just take additional time.
Other potential problem: that this new code doesn't handle some types of edge cases. It's quite hard to figure out what could possibly break in the `ResolutionRequest` code (and I think it would benefit from a larger refactor). We do have a good test coverage for `DependencyGraph` and it seems to work smoothly, so I'm relatively confident we're not breaking edge cases.

Summary:
One of my changeset broke the "ModuleGraph" code without warning earlier because we are using `any`, that equivalent to having no typing at all. This changeset fixes the types so that `ResolutionRequest` is exactly what it actually is: a class usable for any `Module`-looking class, including the normal one, and the "ModuleGraph" one used for Buck builds. That way, the ModuleGraph's `Module` is typechecked against `Moduleish`.
Concretely this change mostly migrates the `Module` to its generic parameter counterpart `TModule` inside `ResolutionRequest`.

Summary: The problem with `bundleOpts` is that it discards Flow typing, so it prevents reinforcing the integration of `Bundler` into `Server`. This changeset removes the `bundleOpts` to solve that issues. Instead, it makes the options explicit so that there is less uncertaintly. I love making options explicit, because they force callsites to take a consicious decision about what is really needed, making them more robust. They also expose oddities that probably needs refatoring, for example having a `resolutionRequest` in the bundle options does not seem correct, it should be an implementation details. Likewise, `onProgress` should probably be exposed differently, as it does not affect the content of the bundle itself.

Summary:
Absolute imports on Windows were broken, I'm not 100% sure when this happens but when I tested Exponent on Windows which uses `rn-cli.config.js` with
```js
getTransformOptions() {
return {
reactNativePath: path.resolve('./node_modules/react-native'),
reactPath: path.resolve('./node_modules/react'),
};
}
```
it seemed to use absolute paths for these modules.
I also tested absolute paths in node repl and it does work for absolute paths of different formats. `C:/root/test.js`, `/root/test.js`, `C:\root\test.js` all do resolve properly to the same module.
To fix this I resolve the absolute path using `path.resolve` on Windows. Noop on other platforms to avoid the overhead since it's not necessary.
**Test plan**
- Tested that it fixed the bug I had when running Exponent on Windows.
- Updated the absolute path test to use forward slashes since this is what happens in practice when using `getTransformOptions`. We can't test all cases on linux since adding the drive letter au

HTTP request URLs don’t include protocol, host and port. Stack frames URLs, on the other hand, contain full URLs. These full URLs are used to get the correct bundle to build the source map from.
The method that creates option objects from URLs therefore now discards leading protocol, host and port to ensure that cached bundles can be reused for symbolication rather than triggering rebuilds.

Summary: I figured out that the uncaught rejection that happens on transform error originated from a "fork" along the chain, where we both "then" on a promise, and return that promise. In that case Node.js, legitimately I think, identifies this as an uncaught rejection case. One solution, in this changeset, is to do the side-effects as part of the promise chain instead of "forking". Another option would be to add an explicit error handler to the additional "then", but it seems we don't have to handle that case here.
