backtrace-python: improve compatibility on macOS release build

Summary:
I noticed the latest homebrew macOS OSS build does not resolve Python frames in
backtrace. It turns out that we need to match the underscore versions of the
function names. See the added comment.

Support TypeSystem <-> SerializableTypeSystem conversion

Summary:
Adds round-trip conversion between `SerializableTypeSystem` and `TypeSystem` instances. (specifically `IndexedTypeSystem`).

- Construction uses `TryFrom<SerializableTypeSystem>`
- Any `TypeSystem` has a default serialization implementating using URI-based export
- Specific `TypeSystem` implementations can override this implementation where appropriate.

fix(scm-prompt): suppress cd output (#985)

Summary:
If a user has a `chpwd` hook that prints output, it will be prepended to the
`dir` variable which breaks the prompt. This change suppresses the output of
`cd` to prevent this.

Alternatively I considered doing `cd -q` to skip running the chpwd hook, but
decided against it.

Pull Request resolved: #985

Test Plan:
```zsh
$ zsh --no-rcs
$ source ~/workspace/github.com/facebook/sapling/eden/scm/contrib/scm-prompt.sh && _scm_prompt
# things should be fine
$ say_hi() { echo hello } && chpwd_functions+=(say_hi) && _scm_prompt
```
prior to this commit, the prompt would be broken. After this commit, it should
be fine.

Background: in my particular case, I have a `chpwd` hook that
[sources custom scripts](https://github.com/vegerot/dotfiles/blob/032f88715fa2911bec6b3c09aa012145bb1dae7e/.zshrc#L250-L252)
depending on the directory, and will tell me if it does so. This was breaking
the prompt, so I added this change to fix it.

AnimatedReorderGroup: ignore small distance animation to workaround V…

…SCode button rendering

Summary:
I notice that when committing, while the optimistic state matches the final
state, the commits below moves up and down unnecessarily.

Upon debugging using a breakpoint in AnimatedReorderGroup when it decides to
animate, I found a 4px animation, and the VSCode buttons [Uncommit] [Split]
were in its "primary" style, with a larger height first rendered. Apparently
the VSCode button then change to the specified "icon" style, with a different
height, but it does not do that in the first render. There are enough pitfalls
in VSCode toolkit we might want to just replace it... but for now let's
workaround the issue by ignoring small distance animation.

Screenshot when hitting the breakpoint - buttons have wrong style and height:
