InterpreterPoolExecutor doesn't respect "thread_name_prefix"

Bug report

Bug description:

InterpreterPoolExecutor takes a thread_name_prefix parameter, but it doesn't propagate to the underlying subinterpreter.

from concurrent.futures import ThreadPoolExecutor
try:
    from concurrent.futures.interpreter import InterpreterPoolExecutor # 3.14+
except ModuleNotFoundError:
    from interpreters_backport.concurrent.futures.interpreter import InterpreterPoolExecutor 

with ThreadPoolExecutor(thread_name_prefix="test_tpe") as tpe_executor:
    tpe_executor.submit(exec, "import threading;print(threading.current_thread().name)")  # 
    
with InterpreterPoolExecutor(thread_name_prefix="test_ipe") as ipe_executor:
    ipe_executor.submit(exec, "import threading;print(threading.current_thread().name)")

从 concurrent.futures.interpreter.InterpreterPoolExecutor 开始，使用 issue 中的 reproducer 将其 thread_name_prefix 行为与 concurrent.futures.ThreadPoolExecutor 进行比较。确认 interpreter worker 报告的名称使用了请求的 prefix，并为所示输出添加或更新 coverage。
