This pull request adds two new CI targets, Mac web_tool_tests_1_2 and Mac web_tool_tests_2_2, to the .ci.yaml configuration. The feedback suggests defining the test_timeout_secs property as an integer rather than a string to prevent potential validation or parsing errors during build scheduling.

I seem to recall that we were starting to drop the shard count from the shard name since it meant we needed to mark each subshard as bringup every time we resharded. Should we just include the shard index in the name going forward?

You're totally right, I forgot I did that in #189040. Fixed.
Mac web_tool_tests runs the 18 web.shard files serially in one shard and takes 23-26 minutes. The shard already picks files by the macos weights in tool_test_durations.json (flutter#195863), so add two duration-balanced subshards, 10.5 and 10.2 minutes of tests each, the same shape as Windows. The names drop the shard count, as flutter#189040 did for Mac tool_integration_tests, so future resharding does not need a bringup round. A follow-up removes Mac web_tool_tests once they are green.

…ngup The two Mac web_tool_tests shards from flutter#196241 are passing in postsubmit. Also drop their test_timeout_secs: the test step is about 10 minutes now, so the 30 minute default is enough.

This will make presubmit faster by reducing the last "long pole" builders, but will incur the cost of another Mac builder with setup/teardown times.
Will follow-up to remove
Mac web_tool_testsonce these two are out of bring-up.Pre-launch Checklist
