CMake uses the `system_name` parameter by default to determine the .obj file extension.
On the Nuttx platform, our `system_name` is `bare matel`,
while CMake only uses `.o` on Linux/Unix systems otherwise, it uses `.obj`.
Therefore, we will change it to `.o` by default.

Add support for running the OS in tickless mode with hrtimer, allowing
the scheduler to operate without periodic ticks while maintaining
high-resolution timer functionality.
Signed-off-by: Chengdong Wang <wangchengdong@lixiang.com>
The hrtimer subsystem is independent of the OS tick mechanism and tickless
mode. It must always be able to reprogram the hardware timer to achieve
nanosecond-level resolution.
A recent update restricted hardware timer reprogramming to tickless mode
only. As a result, hrtimer no longer functions correctly when the scheduler
is running in tick-based mode.
This change removes the incorrect dependency on tickless mode and restores
proper hrtimer operation.

IRQ_TO_NDX() may return a negative value when the IRQ number is invalid
or not mapped. Using this negative value directly as an array index for
g_irqvector causes undefined behavior and potential memory corruption.
This patch adds a bounds check to ensure ndx is non-negative before
accessing the g_irqvector array, returning the error code if invalid.

This patch adds support for the FIOC_FILEPATH ioctl command in the
FAT filesystem, allowing applications to retrieve the full path of
an open file descriptor.
Key features:
- Implements fat_getfilepath() to construct file paths by traversing
parent directories using ".." entries
- Adds fat_findlfnstart() helper to locate the start of LFN sequences
- Supports both FAT12/16 and FAT32 filesystem types
- Handles both regular directories and root directory traversal
This functionality is useful for debugging, logging, and applications
that need to track file paths at runtime.
