rG2318ea10a3af: hwpmc.4: correct stale default values and update diagnostics

Summary

The default values documented for kern.hwpmc.logbuffersize (4KB) and
kern.hwpmc.nbuffers_pcpu (64) have been incorrect since 2981a3420cb1
(2018), which updated the compiled defaults but did not update the
man page.

Correct logbuffersize default from 4KB to 256KB, add 16MB maximum
Correct nbuffers_pcpu default from 64 to 32, document 32MB per-CPU product limit with kern.hwpmc.logbuffersize
Update DIAGNOSTICS section to reflect current warning messages

Sponsored by: NLINK (nlink.com.br)

Test Plan

Verified rendered output with:

man -l share/man/man4/hwpmc.4

mandoc -T lint shows only one pre-existing warning
(IMPLEMENTATION NOTES section order, not introduced by this patch).
