[smart] Add vDSO support for RISC-V architecture and refactor related components
- 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.
