cmake: some formatting fixes Do not include bootloader in flash target when secure boot is enabled. Emit signing warning on all cases where signed apps are enabled (secure boot and signed images) Follow convention of capital letters for SECURE_BOOT_SIGNING_KEY variable, since it is relevant to other components, not just bootloader. Pass signing key and verification key via config, not requiring bootloader to know parent app dir. Misc. variables name corrections

spi_master: compile as C11 due to use of stdatomic.h stdatomic.h is available both in newlib and GCC include directories. Normally (if you invoke the compiler without any flags) GCC include directories are first on the list, so GCC’s stdatomic.h is used. In IDF, we used to pass newlib include path as an extra include directory, so newlib’s stdint.h got included instead. Newlib 2.2.0 stdatomic implementation is compatible with -std=gnu99 but incompatible with -std=gnu11. And GCC doesn’t support atomic_load with -std=gnu99 (it’s a C11 feature). So when we used atomic_load with -std=gnu99, it worked due to newlib’s header. Since we are no longer going to be including newlib headers into IDF, GCC stdatomic will be used instead. Hence, add -std=gnu11 for source files which use atomic features.
