Adding edits (e.g. via `dart fix --apply` are often done with
`List.insert(0, whatnot)` which takes O(n) time.
Here QueueList that can insert fast at both ends is used instead
(and we use `addFirst` instead of `insert(0)`.
On the example from
https://github.com/feinstein/google-i18n-address-dart.git we go from:

I wrote a test that generates 10,000 lines of code, each containing one
violation of `prefer_single_quotes`, computes the fixes for all of the
diagnostics, and applies the 20,000 edits, measuring how long the
application takes.
Before this change the average was 3355.0 ms.
After this change the average is 3.8 ms.
The change was inspired by Jens.

This change shouldn't change any current behaviour, but means all "FilePath" types in the legacy protocol spec will go through a (currently no-op) conversion. The server will be able to replace this conversion based on client capabilities in a future CL.
Because a lot of the generated classes are in analyzer_plugin, this also moves the ClientUriConverter class there.
`pkg\analysis_server\test\src\utilities\json_test.dart` contains tests that the toJson/fromJson methods go through the converter recursively (inc. map keys/values/etc.).

I believe that the tests cover the added behavior (and some existing
behavior), but they aren't complete. I'll add more tests over time, but
for now the test coverage is strictly better than it used to be.

Other than
- the change to enable the lint (in analysis_options.yaml) and
- updates to the generator (in tool) to stop generating 'new',
all of the changes were generated by dartfix.

This reverts commit 86ba29265a.
The replacement API (int.tryParse) has only just been introduced and
is not yet avaiable to internal Google users. I plan to un-do the
commit in about a week once the internal SDK has been updated.
