ANDROID: printk: export symbol for tracepoint_console

Initial kernel bootup logs get overwritten after running
for a long time, and there can be debugging scenario where
we need initial ~100s bootup logs for debugging.
'tracepoint_console' is helping in achieving this purpose.

'tracepoint_console' replaces 'android_vh_log_buf' and
'android_vh_logbuf_pr_cong' vendor hooks in previous GKI kernels.
