tracing/remotes: Add REMOTE_EVENT_CUSTOM_PRINTK() helper

The current REMOTE_EVENT() takes as a __printk argument a string format
and a list of arguments, such as RE_PRINTK("foo=%d bar=%d", foo, bar).
Add a REMOTE_EVENT_CUSTOM_PRINTK() where the __printk argument can be a
function. This intends to support the creation of a "printk" event for
the arm64 nVHE/pKVM hypervisor with a dynamic prototype and by extension
a dynamic print format.
