  Reland "[MC][AsmParser] Diagnose improperly nested .cfi frames"

This showed up when simplifying some large testcase, where the cfi directives
became out of sync with the proc's they enclose.

Now restricted to platforms that support .subsections_via_symbols.

This reverts commit 797b68c0ba699994e1038ac33d3083541482bf19.

Fixes: #72802
