  [profcheck] Add unknown branch weights for inlined strcmp/strncmp (#160455)

The strcmp/strncmp inliner creates new conditional branches but was
failing to add profile metadata. This caused the ProfileVerifierPass to
fail when profcheck is enabled.

This patch fixes the issue by explicitly adding unknown branch weights
to these branches.

Issue #147390
