build(esp-idf): 7 recipes pull midi2 via Component Manager

Drop the dist/midi2.c entry that every recipe re-listed in SRCS
under ${MIDI2_CPP_ROOT}. Each recipe now declares midi2 as a
managed dependency and lists midi2 in REQUIRES so <midi2.h> resolves
through the imported component:

  # idf/main/idf_component.yml
  dependencies:
    idf: ">=5.4"
    midi2:
      git: https://github.com/sauloverissimo/midi2.git
      version: ">=0.3.3"

The Component Manager clones midi2 into managed_components/midi2;
ESP-IDF processes it as a regular component because midi2's top-level
CMakeLists detects ESP_PLATFORM and routes to idf_component_register
(see midi2 v0.3.3).

Recipes touched:

- arduino-nano-esp32-midi2
- esp32-s3-devkitc-usb-midi2
- esp32-p4-devkit-usb-midi2
- esp32-p4-devkit-host-midi2
- esp32-p4-devkit-bridge-midi2
- esp32-p4-devkit-bridge2-midi2
- t-display-s3-midi2

The other midi2_cpp source files (midi2_device.cpp, midi2_ci.cpp,
midi2_host.cpp, midi2_bridge.cpp) keep being compiled inline from
the parent tree until the host helper library shape is finalised.
