Add sleep and delay for task handling

[LuernOutOfOrder]

This pull request introduces kernel task blocking and sleeping primitives, improves documentation, and refines several core kernel mechanisms. The most significant changes are the addition of the sleep primitive and blocked task management, as well as new and updated documentation for kernel structures, primitives, and timing helpers.

Kernel task blocking and sleeping primitives:

• Added a new sleep primitive (with supporting assembly and Rust code) to allow tasks to block themselves for a specified number of ticks, updating their state and moving them between ready and blocked queues as appropriate. This includes the new TaskBlockControl enum and changes to the Task struct to track block reasons. (src/task/primitives.rs, src/arch/riscv32/asm/sleep.S, src/arch/riscv32/asm/mod.rs, src/task/mod.rs, src/main.rs, [1] [2] [3] [4] [5] [6]

• Implemented the task_awake_blocked function, which checks the blocked queue and moves tasks back to the ready queue when their sleep duration has elapsed. This is now called from the timer interrupt handler. (src/task/primitives.rs, src/arch/riscv32/traps/handler.rs, [1] [2] [3]

Documentation improvements:

• Added comprehensive documentation for kernel data structures, primitives, and timing helpers, including invariants and usage notes. (Documentation/kernel/data_structure.md, Documentation/kernel/primitives.md, Documentation/kernel/timing_helpers.md, [1] [2] [3]

Kernel and scheduling changes:

• Modified the scheduler to only requeue tasks as ready if they are not blocked, and added a separate blocked queue. (src/scheduler/mod.rs, src/main.rs, [1] [2]

Testing and test infrastructure:

• Added and updated test coverage for task primitives, including yield and sleep, and integrated the new tests into the test suite. (src/tests/suites.rs, src/tests/arch/riscv32/task/task_context.rs, [1] [2] [3]

Miscellaneous improvements:

• Increased the ROM size in the linker script to accommodate new code. (linkers/linker_test_mode.ld, linkers/linker_test_mode.ldL6-R6)
• Updated version numbers in Cargo.toml and src/info.rs. [1] [2]
• Minor code cleanups and improvements, such as removing unnecessary trait bounds and improving trap handler argument passing. (src/primitives/ring_buff.rs, src/arch/riscv32/asm/trap_entry.S, [1] [2]

These changes lay the groundwork for more advanced task scheduling and blocking mechanisms in the kernel and improve maintainability through better documentation and testing.
