DebugInfo: Drop fake DW_TAG_expression

Break MDExpression off of DebugNode (inherit directly from `MDNode`) and
drop the fake `DW_TAG_expression` tag in the process.

AFAICT, there's no real functionality change here.  The tag was
originally used by `DIDescriptor::isExpression()` to discriminate
between `MDNode`s, but in the new hierarchy we don't need that.

Fixes PR22780.
