Subject: [PATCH] cmake: Removed CMake flags for controlling C standard -
 `CMAKE_C_EXTENSIONS`: Enable/disable compiler-specific extensions -
 `CMAKE_C_STANDARD`: Set C standard (C99, C11) - These variables (as set in
 mbedtls) set the C standard to C99   for ESP-IDF as well, resulting in build
 errors related to   `asm volatile`

(cherry picked from commit e39975969d548572a39875ad29abd88b23285f94)
