[i2c, rtl] Loopback test and other changes

1. Enabled line loopback test
2. Implemented target waiting for host to pull SCL low before stretching the clock
3. Increased depth from 32 to 64 in all four FIFOs
4. Fixed event_nak implementation
5. Added synchronizers for SCL/SDA inputs
6. Modified clock stretching in the target mode: no stretching for the first address match when both en_addr and stop are set; stop is deasserted after this so stretching occurs for the second address match
7. Other minor changes to the target mode
