Conversation
In preparation for adding conditional imports to be able to use different encoding/decoding implementation based on the platform, this PR creates an "internal" library and exports some of the important types for encoding/decoding like `FieldInfo`, `PbFieldType` (renamed as `PbFieldTypeInternal`). This syncs some of cl/613649886.

There was a problem hiding this comment.
I have a few comments; but given:
This syncs the web JSON decoder used internally.
I think we can consider the code reviewed. I think my only blocking comment is that we should update the CI here to test against the vm, dart2js, and dart2wasm.

@devoncarew PTAL. We should merge #1031 first, then rebase and merge this one. |

This syncs the web JSON decoder used internally.
The new decoder uses
js_interopinstead of the Dart standard library toimprove performance when compiled to JS.

master, JS:
PR, JS:
Wasm and VM benchmarks don't change as they keep using the old implementation.
The new implementation is slower with Wasm as it does more JS interop, so we keep using the old one.
