[BUILD] Fix build for esp32

[albkharisov]

Fix for toolchains that alias int32_t to long int. In this way we don't have int in variant of attributes.
If it's defined as strict int32_t, int64_t etc, I think it's better to have strict types everywhere.
ESP-IDF (v5.3.1) toolchain fails to compile as they don't have int in attributes variant list.

Approved the workflow to run CI, but blocking the merge.

I would like first to understand the issue in more details,
to decide the best course of action for the fix.
