* boards: enable CONFIG_FS_LARGEFILE for NuttX boards with MMC/SD
Without large file support, fsblkcnt_t/off_t are 32-bit and statfs
consumers (procfs /fs/usage, df) compute the volume size as
f_bsize * f_blocks in 32 bits, which wraps at 4GB. Boards with an
SD card or eMMC larger than 4GB report the wrong capacity, e.g. a
32GB SD card on FMU-V6X:
nsh> ls -l /dev/mmcsd0
brw-rw-rw-1850212352 /dev/mmcsd0 (= 31914983424 mod 2^32)
nsh> df -h
vfat 1749M 240K 1749M /fs/microsd
With CONFIG_FS_LARGEFILE=y the same card reports the full 29G.
This enables the option on the 77 boards that build the MMC/SD block
driver (CONFIG_MMCSD=y, SDIO or SPI). Boards without removable storage
and constrained-flash targets (CONFIG_BOARD_CONSTRAINED_FLASH=y) are
left unchanged.
Note: on the px4_firmware_nuttx-10.3.0+ branch the 64-bit file types
are additionally gated on CONFIG_HAVE_LONG_LONG, which is only defined
via nuttx/compiler.h include order, making the option unreliable. That
gating is fixed by the companion NuttX backport PR
(PX4/NuttX, branch backport-fs-largefile, upstream commit 92b2f1bd3d3).
Tested on a custom STM32H743 board with 8GB eMMC and on FMU-V6X with a
32GB SD card.
* fix(boards): enable CONFIG_FS_LARGEFILE for MMC/SD variant configs
The test/console/stackcheck/socketcan/sysview/cyphal/debug/cryptotest
variant configs of boards covered by the previous commit were missed,
leaving them with 32-bit off_t. fmu-v5 protected is intentionally
excluded: protected-mode syscall proxies keep 32-bit widths.

* chore(nuttx): bump submodule for FS_LARGEFILE backport
Picks up the backport of upstream NuttX 92b2f1bd3d3, which gates the
64-bit file types on CONFIG_FS_LARGEFILE alone instead of the
include-order-dependent CONFIG_HAVE_LONG_LONG.
