7027d2dfe8 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.

208e83def7 build system: Refactor component.mk to not need component_common.mk
New makefile component_wrapper.mk allows some variables to be set
before component.mk is evaluated. This properly fixes problems with
sdkconfig being hard to access in all phases of the build.

Including component_common.mk is no longer necessary and will print a
deprecation warning for components which use it.
