[material_ui] Reduce web test suite

See #189278 for additional context here.

The web test shards that contain the material_ui and material_ui/example tests take too long to complete (currently ~1 hour, which is the timeout limit). Initial solution involved changing the sharding logic so that the material_ui and material_ui/example tests were assigned to separate shards, but that will need more design (see #189278).

Instead, we are going to reduce the number of test we are running on web, using a similar mechanism to the reduced-test-set tag in flutter/flutter. We can call it something like reduced-web-test-set.

We should only run tests on web that are specifically targeting web behavior or regressions. These test cases can be tagged with reduced-web-test-set. They will run on both web and non-web platforms, whereas tests without that tag will only run on non-web platforms.

Below is a list of test cases targeting web that should use the new test tag (note: the following were identifying via agentic analysis so it's possible some were missed, however I think this subset will still guarantee us solid web coverage):

[material_ui] Reduce the `material_ui` non-wasm web test suite (#12763)

Did some investigation when the material_ui web tests were timing out on one of my PRs.

Turns out their is a bug in the implementation (flutter/packages#12763) which causes a discrepancy in the name of a package to match against when run locally vs. when run on CI:

DartTestCommand._getTagForPackage looks a package up with RepositoryPackage.displayName, which in turn removes everything up to the first path component named packages. On the LUCI bots the repo is checked out into a directory that is itself called packages (e.g. /b/s/w/ir/x/w/packages/packages/material_ui). So the name comes out as packages/material_ui, which never matches the material_ui key.

I am working on a fix!
