Tower I3C/I2C Host Adapter Message combined send support

Easyi3C API provides a message concept to allow user can control the bus freely.

With this concept, users can combine any message and send them out by I2C or I3C protocol.

Message A bus message is a segment of bus waveform start with START/REPEAT_START or end with REPEAT_START/STOP,

7-bit slave addressing, and combined format transactions. The figures below demonstrate it.

As the above figures, we support two types of messages: WriteMsg(), ReadMsg().

For debug I3C/I2C messages transfer, we add a special message: IdleMsg(),  IdleMsg() can add idle time between message transfer.

With many messages combined with a packet, Easyi3C provides the following APIs for packet operate:

1. ez_send_i2c_msgs()
2. ez_send_i3c_msgs()
