text: Title: [CI] Replace `:object_manager` with smaller Bazel targets.
  Body: ### Description
  
  #50885 splits `:object_manager` into smaller targets. Therefore, we can also replace `:object_manager` with smaller targets as dependencies. For example, `pull_manager_test.cc` only requires `"ray/object_manager/pull_manager.h"`, so we don't need to use the entire `object_manager`.
  
  ```
  ray_cc_test(
      name = "pull_manager_test",
      size = "small",
      srcs = [
          "src/ray/object_manager/test/pull_manager_test.cc",
      ],
      tags = ["team:core"],
      deps = [
          ":object_manager",
          "@com_google_googletest//:gtest_main",
      ],
  )
  ```
