This PR brings updates according to the latest changes in the Arduino core:
- Bootloader binaries are now generated from elf files
- Updated CI scripts
- Updated esptoolpy to v4.2.1
- Minor clean-up by removing obsolete code

Resolves #7572

* Add support for Arduino IDE 2.0 Debug

* Update platform.txt

* Add SVD support

* Update configs for IDE 2.0.3

* Update esp32c3.json

* ESP-IDF v4.4.3

* Add IDF libs from v4.4.2

* Implement build time elf2bin for the bootloader

This update includes the following:

- Implemented an additional build step that produces an adjusted bootloader image with updated headers
  according to  selected flash mode and size values. This step is only executed for debugging or uploading
  via debug probes.

- Implemented a basic mechanism to dynamically add an extra UF2 bootloader image if corresponding
  partition is selected (e.g. for Adafruit targets)

- Minor code formatting

* Update get.py to support python 3.10+

* Use try/except to remove version check

* Add changes required for the new memory configs

* IDF release/v4.4 6c5fb29c2c

* IDF release/v4.4 c9140caf8c

When get.py is run in a script the percent-update printouts shown while
downloading the toolchain end up as 100s to 1000s of lines in log files.

When stdout is not a terminal, avoid printing these percentages and
shrink logfiles significantly.  Errors/etc. are still reported as normal.

* Added partition table guide

* Using a custom partition file

* Added some more examples for partitions

* Fixed the app partition offset

* Added bare_minimum_2MB partition table file

* PR review changes

Fixes inability to flash the bootloader with esptool 4.x on device with flash size different than the default

This fixes possible issues when developers specify arbitrary partition files
using relative or absolute paths.

Additionally, hyphens in filenames are replaced with underscores to
avoid compilation warnings "ISO C++11 requires whitespace after the macro name"

Resolves platformio/platform-espressif32#787

Description of Change

Fixes IPAddress INADDR_NONE declaration when using Arduino WiFi or ETH.
This symbol was defined as 0xffffffff by lwip /inet.h, making it impossible to use INADDR_NONE correctly.

This PR only works when <wifi-provisioning/wifi_config.h> has a modification to include <lwip/ip4_addr.h> instead of <lwip/inet.h>. This will be done directly to the sdk folder in the github structure and it has been fixed in IDF by a separated Merge Request. This will be reflected in the future, for good.

Tests scenarios

This PR was tested with all Arduino WiFi examples, including AsyncUDP. Also with ETH examples.
It was also tested for #6610 test cases.
Testing done for ESP32, ESP32-S2, ESP32-C3 and ESP32-S3.

This PR adds support for uploading additional flash images (e.g. Adafruit Tiny UF2 bootloader) specified in board manifests.

Additionally, the PR switches the PlatformIO CI script to the upstream version of the ESP32 dev-platform (basically reverts changes introduced in #5387 as they are no longer required).

Fixes: #6508

* Add certificate bundle capability to WiFiClientSecure

Enable usage of the ESP32 IDF's certificate bundle for WiFiClientSecure connections.

Adds the ability to load a bundle or root certificates and use them for authenticating SSL servers.

Based on work from Onno-Dirkzwager, Duckle29, kubo6472, meltdown03, kinafu and others.

* [FEATURE]  ARDUINO_PARTITION_xxx build flag

Proposition: adding `-DARDUINO_PARTITION_{build.partitions}` flag to make the build partition information available at compile time.

Use cas example:

```C
#if defined ARDUINO_PARTITION_default
  // prevent compilation
  #error "This sketch needs 'Minimal SPIFFS' partition scheme to compile" 
  // or disable sketch features that need flash space
  #define USE_HUGE_BITMAP_IMAGES false
#endif
```

* Adding -DARDUINO_PARTITION_{build.partitions} (see #5804)

* Update toolchain to 2021r2 (#5828)
* Update C3 libs to support only ECO3 and newer
