#86850 did work to make manifest generation cheaper for NativeRuntimeEventSource, but I'm not clear on why the answer wasn't instead to just not do anything for manifest generation for NativeRuntimeEventSource, which is what this PR does.

On my machine, this lowers time-to-main by 33%, including removing all of the dynamic methods / JIT'ing work noted in #90405.

@tommcdon, @davmason, @brianrob, am I missing something?
