- Implemented vDSO functionality for the RISC-V architecture, including the necessary source files and linker scripts.
- Introduced a new `vdso_sys.c` file for RISC-V, containing functions to handle time retrieval using the vDSO mechanism.
- Created architecture-specific linker scripts (`vdso.lds.S`) for both AArch64 and RISC-V.
- Updated the build system to support vDSO compilation for RISC-V, including necessary adjustments in `SConstruct` files.
- Refactored existing vDSO code to improve compatibility and maintainability across architectures.
- Adjusted the maximum number of PTY devices in the terminal configuration from 64 to 32 for better resource management.
- Fixed minor issues in existing code, including correcting the path for the vDSO shared library and ensuring proper function definitions.

This change introduces the `lwp_runtime.c` component, which provides the
necessary runtime environment for the init process, including boot scripts,
shutdown, and poweroff functionalities. The initialization logic has been
moved from `lwp.c` to this new file, enhancing modularity and flexibility
in handling LWP runtime tasks.
Changes:
- Moved the `lwp_startup` function from `lwp.c` to `lwp_runtime.c` to handle
system initialization and runtime environment setup.
- Added `lwp_teardown` placeholder for system shutdown and cleanup tasks in
the future (though not yet implemented).
- Introduced the `LWP_USING_RUNTIME` configuration option in `Kconfig` to
conditionally enable the runtime environment.
- Updated the `SConscript` to conditionally include `lwp_runtime.c` based on
the `LWP_USING_RUNTIME` configuration.
- Removed the old `lwp_startup` code from `lwp.c`, simplifying the file.

The `LWP_CONSOLE_INPUT_BUFFER_SIZE` is a legacy config option for TTY
driver used in smart. Since the driver is updated, there's no dependency
of this option any more.
Changes:
- Removed unused Kconfig option `LWP_CONSOLE_INPUT_BUFFER_SIZE`

In this patch, a hook list has been introduced to address the concerns
regarding coupling issues arising from modifications to the serial code
for integrating TTY logic.
