See eb815be907 for more information about this feature.
The proto modifier indicates that a property declared using `x: T` syntax is actually present on the prototype object of the class, rather than an own property.
The proto and static modifiers are mutually exclusive, as class declarations don't simultaneously define the static prototype object, as they do the instance prototype.
This syntax is only supported on declared classes, not object types, interfaces, or runtime class declarations, and as such should only appear in library definitions.
Fixes gh-8041

The `all` option landed in https://github.com/babel/babel/pull/7934/files#diff-3a8233bcd2766d2c7d87f23f944f7726R3 but it is only exposed from the plugin, not the preset, so this exposes it there too since the flow preset is what we want people to use.

The filed bug was for `-0`, but I also realize that `numericLiteral` also shouldn't be getting `-Infinity`/`Infinity` or `NaN` since those just get stringified with the JS-standard stringification logic which means we get a reference to `NaN` or `Infinity` identifiers, which could have been shadowed in a local scope and thus not be the right value. I've avoided that by generating `NaN` as `0/0` and the infinity values as `1/0` and `-1/0`.

Currently the `opts.filename` value exposed to plugins is just whatever the user passed. While it _could_ be relative to the working directory, if Babel was passed an absolute URL, it'll be absolute.
This PR explicitly ensures the filename is a relative path based on the working directory. This also exposes an officially endorsed API for reading the working directory path.
