Subject: [PATCH] global: Kconfig: add CONFIG_IDF_TARGET_LINUX

Can be used in target-specific C code to distinguish when Linux target
is used.

Also don't enable CONFIG_APP_BUILD_GENERATE_BINARIES and
CONFIG_APP_BUILD_BOOTLOADER when building for Linux, since the
bootloader is not used. CONFIG_APP_BUILD_GENERATE_BINARIES might make
sense in some cases, can be re-enabled later.
