Eliminate lambdas from tracing helper macro

In the change with ID Ibee1e7dc5021296bdb5871dec59d8d4978fcf0c9,
we introduced lambdas at the tracing sites so that we could
conditionally execute the code to generate the tracing string only when
tracing was enabled. However, it seems like the introduction of the
lambdas, especially ones that capture everything by reference, have
added a performance burden, causing ~5% increase in latency in the input
pipeline.

In this CL, we remove the lambdas from the tracing sites, and instead
rely on the expression evaluation guarantees of the ternary to ensure
that the expression to generate the trace message will only be evaluated
when the condition is true.
