esp_system: Fix esp32c2/esp32c3/esp32h2 TLS size

The change fixes thread-local-storage size by removing .srodata section
from it. It initially was included in TLS section by mistake.
The issue was found when stack size increased after building applications
with GCC-11.1 compiler. Stack size became bigger because some new data
appeared in .srodata. See more details here:
