54b0066a69 libs/libc: Fix divide-by-zero in stat() with large filesystem block sizes
blksize_t is currently defined as int16_t, which overflows when a
filesystem reports a block size larger than 32767 bytes. This causes
st_blksize to become zero, leading to an integer divide-by-zero when
st_blocks is calculated in stat().

Widen blksize_t to int32_t to support larger filesystem block sizes.

Update nuttx_blksize_t in include/nuttx/fs/hostfs.h to keep it
consistent with include/sys/types.h.

struct geometry.geo_sectorsize (include/nuttx/fs/ioctl.h) is also
typed blksize_t, so every debug print of that field using a 16-bit
format specifier is updated to PRId32 to match the new width:
drivers/misc/ramdisk.c, drivers/mmcsd/mmcsd_spi.c, drivers/mtd/ftl.c,
fs/driver/fs_blockmerge.c, drivers/mtd/smart.c,
drivers/usbhost/usbhost_storage.c, drivers/mmcsd/mmcsd_sdio.c,
arch/arm/src/s32k1xx/s32k1xx_eeeprom.c,
arch/arm/src/lc823450/lc823450_mmcl.c.

0dccc8ba21 include/debug.h: Move to include/nuttx/debug.h
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.
