This should fix https://github.com/flutter/flutter/issues/126178
When we don't pass a `--concurrency` flag to the test package, it uses a default based on the number of cores that are on the machine. However, the web test platform itself serializes all these requests anyway, which can lead to the test package timing out. This is because from the test package's perspective, it has already started the loading process on a number of suites which are simply waiting for other test suites to compile and run. The ones that wait the longest can run up against the test packages 12 minute timeout for loading a given suite, even though they haven't actually started to try to load.
Instead, we should always pass `--concurrency=1` to the test package so that it doesn't attempt to start loads concurrently in the first place.

Speedup coverage test runs by using (new) coverage handle with caching.
On a `flutter test --coverage` run on `packages/flutter` the runtime goes from ~828 seconds to ~617 seconds, or a ~25% reduction in time spent (testing without coverage takes ~236 seconds so the overhead of `--coverage` in this case goes from ~592 seconds to ~381 seconds, or a ~35% reduction).
In https://github.com/flutter/flutter/pull/103771, we rolled
dependencies in Flutter, which triggered an update of package:coverage
to v1.3.1. The new version includes
https://github.com/dart-lang/coverage/pull/370 in which two deprecations
landed:
* The `Resolver` default constructor was deprecated and replaced with
the `Resolver.create` static factory method, which unfortunately
happens to be async.
* The `packagesPath` parameter to `HitMap.parseJson`, which takes the
path to the `.packages` file of the package for which coverage is to
be collected, was deprecated. This parameter was replaced with
`packagePath` in https://github.com/dart-lang/coverage/pull/370 which
was part of the overall deprecation of the .packages file in Dart
itself https://github.com/dart-lang/sdk/issues/48272. The overall goal
being that end-user code shouldn't need to know about implementation
details such as whether dependency information is stored in a
.packages file or a package_info.json file, but rather use the
package_config package to obtain the package metadata and perform
other functions such as resolving its dependencies to filesystem
paths. packagesPath was replaced by packagePath, which takes the path
to the package directory itself. Internally, package:coverage then
uses package_config to do the rest of the package/script URI
resolution to filesystem paths.
This migrates off the deprecated `packagesPath` parameter to the
replacement `packagePath` paramter.
