nsh_fileapp() could not apply an application's Kconfig-configured
priority/stacksize via posix_spawn() under CONFIG_BUILD_KERNEL, because
the registry table (struct builtin_s / g_builtins[]) was gated on
CONFIG_BUILTIN, which depends on !BUILD_KERNEL. Those settings were
silently ignored in KERNEL builds.
CONFIG_BUILTIN conflates the table with main_t-based dispatch, which is
meaningless under CONFIG_BUILD_KERNEL. Add a hidden derived symbol,
APP_REGISTRY, that tracks table availability independently of dispatch:
config APP_REGISTRY
bool
default y if BUILTIN || BUILD_KERNEL
Switch the guards on the table itself (Make.defs, builtin.h) from
CONFIG_BUILTIN to CONFIG_APP_REGISTRY. Call sites that dereference
builtin->main stay gated on CONFIG_BUILTIN and remain unreachable
under CONFIG_BUILD_KERNEL.

Squashed commit of the following:
Correct some additional compile-related issues.
Move include/nuttx/binfmt/builtin.h to include/nuttx/lib/builtin.h. Move apps/builtin/lib_builtin_forindex.c to libs/libc/builtin/lib_builtin_forindex.c.
Move binfmt/libbuiltin to libs/libc/builtin. There are calls made directly from apps/nshlib into this logic and hence, must be part of a library that can be shared between the OS and applications.
