esp32: update for toolchain version v2

[gschorcht]

Description

This PR changes the reference to another commit of the precompiled ESP32 toolchain repository to update the toolchain to a version that is required to fix issue RIOT-OS/RIOT#13133.

Test

Compilation of all examples/tests in current RIOT master should succeed.

Dependencies

Requires PR RIOT-OS/RIOT#13141

ACK.

rollout will have to wait until after release testing, though...

[gschorcht]

Wow, very fast. Thanks.

So we have also to merge and backport RIOT-OS/RIOT#13141. Otherwise, a user who is generating docker image from the Dockerfile would run into compilation errors.

The current RIOT master should work with the updated toolchain too.

Yeah, it's just that during these weeks, I try to change as little as possible in the CI infrastructure. Losing half a day on a revert-and-redeploy-and-retest cycle is painful for the people trying to get backports and fixes CIed. (Not that I think this PR would cause that.)

@kaspar030 The release is out. We could try to roll out that change now.

The fix in PR RIOT-OS/RIOT#13141 was backported to the release with PR RIOT-OS/RIOT#13144. So there should be no risk to roll it out. Once it is rolled out, we can revert RIOT-OS/RIOT#13140.
