feat(bsp_selector): Component for selection BSP in menuconfig

[espzav]

ESP-BSP Pull Request checklist

• Version of modified component bumped
• CI passing

Change description

• Created BSP Selector component - for select BSP from menuconfig
• It should work from IDF 5.3
• We keep old bsp_ext.py for CI
• The CI removes bsp_selector component in examples, which are added to each BSP
• Added ignore warnings for warning: unknown kconfig symbol* - I didn't find any other solution for it.
• • I tried to remove this configuration option from sdkconfig and add it into presets - not working

---

Note

Introduces a new components/bsp_selector component to choose BSPs via menuconfig, with Kconfig, CMakeLists.txt fail-safe when none selected, idf_component.yml conditional deps to BSPs, README, and license.

• Replaces hardcoded BSP deps in examples with bsp_selector; adds per-board sdkconfig.bsp.* files setting CONFIG_BSP_SELECT_* and updates defaults
• Updates CI: bumps component manager to 2.4.*, uploads components/bsp_selector, adds ignore rule for warning: unknown kconfig symbol*, and adjusts scripts (.github/ci/bsp_example_update.py, examples/bsp_ext.py) to remove bsp_selector when pinning a specific BSP for builds
• Enhances PR checklist to require adding new BSPs to bsp_selector Kconfig/idf_component.yml

@tore-espressif @PetrESP PTAL

[PetrESP]

In my opinion adding this component is a the cleanest solution for this issue and I agree with this concept

Tested locally and it works well on my debian laptop.
