[CI] Replace :object_manager with smaller Bazel targets.

[kevin85421]

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",
    ],
)
