Summary:
Move and create an empty rule that redirects as well, to handle //arvr rules
Need to do this way, since ovrsource sync rules are in different repo.
allow_many_files
allow-large-files
Steps:
- [X] Move glog from xplat/third-party to /third-party
- [ ] Update references in ovrsource to translate to //third-party instead of //xplat/third-party
- [ ] Get rid of temporary rule
- [ ] Update fbsource/third-party/glog to 0.3.5 (what we have in ovrsource)
Changelog: [Internal] Update reference for glog from xplat/third-party to /third-party.

Summary:
This diff changes how arbitrary-node-replacing (aka `RootShadowNode::clone`) algorithm works.
Original implementation worked this way: We specified a node that needs to be replaced and a new replacement node. Then the algorithm finds a node with *the same family* as given the to-be-replaced node and replaced that with a given replacement.
The problem with this approach is that we are replacing a node that we have very little info about (we only know that it shares the same family as specified one). At the same time, we build the replacement based on the exact node that we have. Then imagine the case in which the "target" node can progress/change between a moment where we get a reference to it and a moment where we are trying to clone the tree. In this case, we will replace a "progressed" node with a modified version of the obsolete node.
Practically speaking, it was possible that during a state update we were replacing a node that just got new children with a bit older version of that with old children but with a new state.
How to deal with it? This diff introduces a new interface for this method that allows separating the target node and the actual act of cloning the corresponding node. Instead of specifying actual replacement, we now specify a function that performs the cloning/transformation on-demand on the very exact node that was in the tree at the moment of cloning.
This change does not change/affect any ownership-related relationships between trees and/or nodes.
Ideally, probably, the interface should accept ShadowNodeFamily instance instead of a ShadowNode instance to make the behavior very clear but that requires a bunch of low-level changes that it out of the scope of this fix.

Summary:
This is the first diff in the journey of removing `enable_shared_from_this` from `ShadowNode` class.
In general, using `enable_shared_from_this` is fine, it's a normal standard feature and there is nothing wrong with that... besides the fact that using this thing is usually an indication of overall poor design.
In Fabric, we don't really have a good reason for that, I think in all cases it can be avoided, so I think we should remove that.
Removing that is also code-size and perf win.
This particular diff changes the signature of `RootShadowNode::clone()` which allows removing the necessity of usage `.shared_from_this()` from callsites.
The rest changes are purely cosmetical.

Summary:
First of all, seems it's the right thing to do. Fabric C++ code is cross-platfrom and should run on *all* platforms including Windows, Linux, and Mac.
While we don't have a real *production* use cases where we need compilation for desktops, having CXX target is really handy for two reasons:
* It simplifies local test running process. Instead of going to `/fbandroid/` and executing something like `buck test fbsource//xplat/js/react-native-github/ReactCommon/fabric/core:coreAndroid` (note the suffix). We can just do `buck test fbsource//xplat/js/react-native-github/ReactCommon/fabric/core:core` everywhere and it works now out of the box. Running tests with "Apple" flavor never worked for me.
* It allows creating synthetic benchmark tests (using Google Benchmark) that can be used as a rough approximation of code micro-optimizations.

Summary:
Previously we computed the list of nodes that need to be notified about layout changes using a list of mutation instructions. That was fine, but that's not really compatible with some other changes that I plan to make, so I decided to change it (make it better).
Besides the better design (debatable; fewer dependencies to unrelated moving pieces), here is why I believe the new way is more performant:
* The new approach has no `dynamic_casts`, whereas the previous has tons of them (two per a mutation). If a `dynamic_cast` takes 10 ns, for 500 nodes it can take up to 5ms only for casts. (Non-scientific assumption.)
* After removing dependency to mutation instruction, we can enable flattening for views which have `onLayout` event.

Summary:
@public
In order to encapsulate property access on `YGStyle`, as a first measure we wrap all fields with accessors.
This will e.g. enable dynamic property storage and instrumentation in the future.
All accessors have a `const` version that allows direct access via `const&`. For mutation, bit fields are wrapped with a custom reference object.
This style allows for the least amount of changes in client code. Property access simply needs appended parens, eg `style.direction` becomes `style.direction`.

Summary:
As a comment above changed lines states, RootShadowNode is a special one because it layouts itself. In normal case some parent node layouts its children, and it also checks getHasNewLayout flag. So, in the case of RootShadowNode it has to check its own flag by itself.
That fix should save some resources and generally correct.
After the change, changing a state of some node does not cause relayout process. If dirtying is required, the component should call `dirtyLayout()` explicitly in the constructor or in `adopt` method.
