refactor(rtcio): remove duplicated macros in rtc_io_hal.h (IDFGH-16862)

[puyogo-suzuki]

Description

This PR removes the redundant, duplicated definitions of the following macros from components/hal/include/hal/rtc_io_hal.h.

• rtcio_hal_get_level
• rtcio_hal_set_level

I found that these two macros were defined twice (identically) within the same #if block.
This change removes the unnecessary definition for each macro.
The compiled output and behavior of the code remain unchanged.

Testing

I have tested rtc_gpio_set_level and rtc_gpio_get_level on ESP32-DevKitC.
