This PRs updates to Browserslist 4.14, and uses the new supports es6-module query instead of our custom logic to build the esmodules: true query.

I wanted to include this in #12189, but since it's just a small refactoring I moved it to a separate PR.

In theory this shouldn't have changed, but:

• node is removed because Browserslist uses compat-table which doesn't include data for Node.js. It's not a problem, because all the transforms required for Node.js 13.2 are required for the other browsers in this query anyway 🤷
• android is changed because compat-table only keeps data for the last version. I kind of expected Browserslist to automatically use the Chrome version (like we do in our generated compat data) since we are using the mobileToDesktop: true Browserslist option, but again it's not observable since android 61 is already covered by chrome 61 in these targets.

This will become a breaking change, if we decide { esmodule: true } should intersect other queries (babel/rfcs#2 (comment)), i.e. B({ esmodule: true }) ∩ B({ android: 78 }) will no longer be B({ android: 78 }) but B({ android: 81 }), where B is the browsers set returned from @babel/helper-compilation-targets. Likewise for node.

@ai I think it is a bug if supports feature query does not respect mobileToDesktop: true

npx browserslist --mobile-to-desktop "supports es6-module"

should contain android 61.

[nicolo-ribaudo]

I realized that we won't be able to use a Browserslist-based intersection anyway.

Currently targets: ["chrome 30"] resolves to "compile everything down to chrome 30, but targets: ["chrome 30 and supports es6-module"] resolves to an empty set because there isn't any browser that both is chrome 30 and supports esm.

The query should have been chrome >= 30 and supports es6-module, but it given how targets has always being working users probably rely on >= being optional.
