esp32: Don't disable component manager when updating submodules.

- Reverts the change from ec527a1 - since later change cccac2c we
  no longer exit CMake early to get the submodule list, so it's OK
  to run component manager during this phase.

- Fixes issue where "make submodules BOARD=ESP32_GENERIC_S3" (or any other
  board that depends on USB) would fail due to missing component(s).

This work was funded through GitHub Sponsors.
