302370720e [driver][serial] V1]: fix correct data loss logic when RX ring buffer is full 
In the serial ISR (`rt_hw_serial_isr`), the previous logic for handling a full RX FIFO was flawed. When the buffer was filled, it would increment `get_index` (`get_index += 1`).

This had two negative consequences:
1.  It effectively discarded the oldest byte of data prematurely.
2.  It reduced the usable capacity of a buffer of size N to N-1. For example, a 64-byte buffer could only ever hold 63 readable bytes after becoming full.

This patch corrects the behavior by implementing a standard overwriting ring buffer strategy. When the buffer is full, the logic is changed to `get_index = put_index`.

This ensures that:
- When new data arrives, it correctly overwrites the oldest data.
- The `get_index` is advanced along with the `put_index`, correctly marking the new start of the buffer.
- The full N-byte capacity of the buffer is utilized, always storing the N most recent bytes.

This change resolves the unexpected data loss and makes the buffer behavior correct and predictable.

82bb104f65 fix(serial_v2): tx_fifo->rb.buffer_ptr not init when RT_DEVICE_FLAG_DMA_TX and RT_SERIAL_TX_BLOCKING 
为什么提交这份PR (why to submit this PR)
serial_v2驱动框架，rt_serial_tx_enable()函数，在 DMA阻塞发送(RT_DEVICE_FLAG_DMA_TX and RT_SERIAL_TX_BLOCKING) 的时候，使用rt_malloc分配了tx_fifo内存，但是并未对tx_fifo->rb.buffer_ptr指针进行初始化（rt_malloc不会自动初始化内存），因此可能导致buffer_ptr是一个随机指针。但是rt_serail_write()函数需要根据tx_fifo->rb.buffer_ptr是否为RT_NULL来判断是调用_serial_fifo_tx_blocking_nbuf()还是_serial_fifo_tx_blocking_buf()。

由于tx_fifo->rb.buffer_ptr可能是一个随机值（不一定为RT_NULL=0），导致RT_DEVICE_FLAG_DMA_TX and RT_SERIAL_TX_BLOCKING模式下调用了_serial_fifo_tx_blocking_buf()，但是rb没有真正开辟内存空间，导致内存异常

你的解决方案是什么 (what is your solution)
rt_serial_tx_enable()，在DMA阻塞发送分支下，对tx_fifo->rb.buffer_ptr进行初始化，赋值为RT_NULL。
