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

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).

* [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

* Update toolchain

* Update package_esp32_index.template.json

* add optional component dependencies after Kconfig options are known (#5404)

Until this commit, Kconfig options (e.g. CONFIG_TINYUSB_ENABLED) were
used in conditions preceding idf_component_register to determine which
components need to be added to `arduino` component requirements.
However the Kconfig options aren't known at the early expansion stage,
when the component CMakeLists.txt files are expanded the first time
and requirements are evaluated. So all the conditions evaluated as if
the options were not set.
This commit changes the logic to only add these components as
dependencies when the Kconfig options are known. Dependencies become
"weak", which means that if one of the components isn't included into
the build for some reason, it is not added as a dependency.
This may happen, for example, if the component is not present in the
`components` directory or is excluded by setting `COMPONENTS` variable
in the project CMakeLists.txt file.
This also ensures that if the component is not present, it will not be
added as a dependency, and this will allow the build to proceed.

Follow-up to https://github.com/espressif/arduino-esp32/pull/5391.
Closes https://github.com/espressif/arduino-esp32/issues/5319.

* IDF master d93887f9f

* PlatformIO updates for CI (#5387)

* Update PlatformIO CI build script

- Switch to the latest toolchains 8.4.0 for ESP32, ESP32S2, ESP32C3
- Use PlatformIO from master branch for better robustness

* Update package.json for PlatformIO

This is very much still work in progress and much more will change before the final 2.0.0

Some APIs have changed. New libraries have been added. LittleFS included.
