esp32: Provision to redirect .bss to external ram through linker fragments Include external ram section in the linker template to process it through linker script generation mechanism. This enables redirection of .bss section to external memory using linker fragments libnet80211, libpp, libbt, liblwip: Redirect .bss through fragments

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: https://github.com/gcc-mirror/gcc/commit/adce62f53d8ad00e8110a6a2de7962d7a850de16
