hadrian: Dump STG when ticky is enabled

This changes the "ticky" modifier to enable dumping of final STG as this
is generally needed to make sense of the ticky profiles.

hadrian: Add a viaLlvmBackend modifier

Note that this also slightly changes the semantics of these flavours as
we only use LLVM for >= stage1 builds.

rts: Flush eventlog buffers from flushEventLog

As noted in #18043, flushTrace failed flush anything beyond the writer.
This means that a significant amount of data sitting in capability-local
event buffers may never get flushed, despite the users' pleads for us to
flush.

Fix this by making flushEventLog flush all of the event buffers before
flushing the writer.

Fixes #18043.
