This commit moves shared builtin information out of binfmt/libbuiltin and into libs/libc/builtin where it can be shared. This should permit builtin application in the PROTECTED build where binfmt/libbuiltin is not available in user space. 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.

---help---
Enable support for builtin applications. This features assigns a string
name to an application and in addition if FS_BINFS is defined, retaining
those names in a file system from which they can be executed. This feature
is also the underlying requirement to support built-in applications in the
NuttShell (NSH).
libc/builtin: support per-application priority/stacksize under KERNEL build. 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. Signed-off-by: liang.huang <liang.huang@houmo.ai>

config APP_REGISTRY
bool
default y if BUILTIN || BUILD_KERNEL
---help---
Hidden option indicating that the compile-time name/priority/stacksize
registry table for applications (struct builtin_s / g_builtins[]) is
available. This is a broader condition than BUILTIN: BUILD_KERNEL
cannot select BUILTIN (main_t dispatch is meaningless when the caller
and the application are in different address spaces), but it still
needs this table so that posix_spawn() can pick up each application's
configured priority and stack size.
