cpu/esp32: changes to use ESP-IDF HAL/LL API

[gschorcht]

Contribution description

This PR is provides all changes that are required to support other variants (families) of the ESP32 SoC series.

As a follow up to PR #17601, this PR contains all the changes to not use the ESP32 at the register level, but to use the ESP-IDF HAL and LL APIs. HAL and LL APIs provide an interface that is independent on used ESP32 SoC family. This allows the support of other variants of the ESP32 SoC series with very little effort.

Since this PR is a splitt-off of a subsequent PR for the ESP32C3 variant, it already contains some changes which

• make the ESP32 implementation independent of the used ESP32 SoC family
• make the ESP32 implementation independent of the Xtensa architecture
• contains conditional code for other ESP32 SoC variants
• takes the RISC-V based ESP32 architecture into account.

It was impossible to completely clean up the fork from the aforementioned changes and would not have made sense.

This PR includes PR #17601 for the moment to be compilable. Once PR #17601 is merged, this PR is rebased. The first additional commit of this PR is e2ecce7.

Testing procedure

Green CI with test run.

@benpicco I'm sorry for producing so many PRs and CI compilation load (for some even twice, I wish the hash value problem was already solved), but these are the changes as split-offs from this PR that are small enough and can be compiled independently.

PR #18246, #18247, #18248, #18249, #18250, #18252, and #18252 are all changes necessary to use the ESP-IDF HAL/LL except for the peripherals. Once these PRs are merged, I can provide the changes PR by PR for the peripherals (21 commits).

@benpicco Do you think there is a chance to continue reviewing and merging the small spin-offs from this PR in the next few days? They are the prerequisite for me to split PR #17842 into smaller PRs, which in turn are the prerequisite for PR #17844, the first ESP32x variant support. Not that we are finally using ESP-IDF 4.4 when it is already obsolete 😉 ESP-IDF 5.0 seems to be already released and supports the very interesting ESP32H2 RISC-V based SoC with BLE 5.0 and IEEE802.15.4.

All splitt-offs were merged, so we can close this PR.
