Increase MOD_LINELEN from 64 to 256 so complete /proc/modules lines fit the formatting buffer on 64-bit targets.

modprocfs_callback() formatted each line into line[64] with snprintf()
and passed snprintf()'s return value, the length the line would have
had, to procfs_memcpy() as the source length. A module name longer
than a few characters therefore made the copy read past the end of
the line buffer and hand kernel heap memory to the reader, and grew
totalsize by the difference.
Use procfs_snprintf(), which returns the length actually written, as
the other procfs entries already do.

Align the NuttX open(2) flag constants with the Linux asm-generic
values so that the FUSE wire protocol and other cross-platform
interfaces work without conversion.
All code that used '(flags & O_RDONLY)' as a bitmask check (always 0
now that O_RDONLY=0) has been updated to use '(flags & O_ACCMODE)'
comparisons.
The NUTTX_O_* constants in include/nuttx/fs/hostfs.h are updated to
match, and the sim hostfs open flag mapping is fixed.

debug.h is a NuttX-specific, non-POSIX header. Placing it in the
top-level include/ directory creates naming conflicts with external
projects that define their own debug.h.
This commit moves the canonical header to include/nuttx/debug.h,
following the NuttX convention for non-POSIX/non-standard headers,
and updates all in-tree references.
A backward-compatibility shim is left at include/debug.h that
emits a deprecation #warning and re-includes <nuttx/debug.h>,
allowing out-of-tree code to continue building while migrating.

Renaming "modlib" to "libelf" is more in line with the implementation content,
which makes it easier for individual developers to understand the capabilities of this module.

1. use '__attribute__((constructor))' mark initialize function
2. use '__attribute__((destructor))' mark uninitialize function
3. compile module with -fvisibility=hidden. use `__attribute__((visibility("default")))`
mark is need export symbol.so not need module_initialize to initialize export symbol.

Pros:
* Reduce code differences
* Smaller allocations for !CONFIG_ARCH_USE_MODULE_TEXT
Cons:
* Likely to use more memory for !CONFIG_ARCH_USE_MODULE_TEXT in total
Tested with:
* sim:module on macOS
* esp32-devkit:nsh + CONFIG_MODULE on qemu
* lm3s6965-ek:qemu-protected + CONFIG_EXAMPLES_SOTEST on qemu
