CFG_TUD_MSC_EP_BUFSIZE: 4096 → (HS ? 4096 : 1024). Keep the big buffer for
HS where it actually amortises CBW overhead at iperf-class throughput; FS
peaks around ~830 kBps so 1 KB is plenty and the example now fits on
small-RAM MCUs (lpc11/13, samd11, kinetis_kl, stm32f0/l0, stm32f1, etc.).
Also dedupe CDC_TX_BUFSIZE = CDC_RX_BUFSIZE.
Drops the previously-needed skip.txt — verified builds locally on
lpcxpresso1347, cynthion_d11, lpcxpresso11u37/u68, stm32f072disco/eval,
frdm_kl25z, stm32l052dap52.

The example uses 4 KB MSC bulk buffer + 2-4 KB CDC buffers to push USB
throughput, which overflows on lpcxpresso1347 (RamUsb2) and cynthion_d11.
Skip the same MCU set as net_lwip_webserver — these targets don't have
the RAM headroom to benefit from throughput tuning anyway.

The bigger TCP_WND/PBUF_POOL/MEMP_NUM_TCP_SEG and the always-on iperf
overflowed SRAM on stm32c0/f1/wb, lpc11/13, samd11. Add LWIP_HIGH_THROUGHPUT
gate (defined in tusb_config.h, consumed by lwipopts.h) so RAM-tight MCUs
keep the original modest buffers and skip iperf, while RAM-rich targets
(max32*/stm32f2/f4/f7/h5/h7/h7rs/u5/n6, rp2040, mimxrt1xxx, nrf5x) keep
the throughput tuning needed for the iperf HIL test.

IAR is only supported with CMake. Remove all IAR-specific references
from the Make build system including toolchain files, SRC_S_IAR,
LD_FILE_IAR variables, and IAR toolchain detection.
Also fix GET_SECTOR_COUNT truncation in msc_file_explorer and
broken formatting in stm32f7 board_uart_write.

- Add lib/fatfs to deps_mandatory in get_deps.py, pinned to R0.16
(commit 30ca13c6) from github.com/abbrev/fatfs mirror
- Move TinyUSB custom ffconf.h to examples/host/msc_file_explorer/src/
with project-specific settings: FF_CODE_PAGE=437, FF_USE_LFN=1,
FF_FS_RPATH=2, FF_VOLUMES=4, FF_FS_NORTC=1
- get_deps.py removes stock ffconf.h after clone to avoid conflict
- Remove vendored fatfs source files from git tracking
FatFS R0.16 includes important fixes since R0.15:
- Fixed FAT32 FsInfo regression (forced full FAT scan on f_getfree)
- Fixed f_readdir infinite loop (from R0.15b)
- f_getcwd/.. now works on exFAT
- Added FF_FS_CRTIME support
Use separate endpoint numbers (EP1 OUT, EP2 IN) on MCUs with shared
FIFO that cannot support the same endpoint number in both directions.
Also add missing static qualifier to print_musb_info().
