Ben Meadors 2a20ee5954 ESP32: link via @response files across the family, not just P4 
The rak_wismesh_tap_v2-tft link failed on CI with "sh: Argument list too
long": the device-ui bump in #11214 grew the MUI object list enough that
the linker command line crossed the kernel exec arg limit (this env's long
name lengthens every object path, so it tipped first).

extra_scripts/ld_response_file.py already solves this for esp32p4; promote
it to esp32_common so every ESP32 target links through a response file,
and drop the now-inherited entry from esp32p4.ini.

Verified by building rak_wismesh_tap_v2-tft at the failing commit plus this
fix: links clean (macOS's exec arg limit is smaller than the Linux one that
tripped CI, so an unwrapped link could not have passed).
