[RemoveDI][NFC] Rename DPValue->DbgRecord in comments and varnames (#84939)

This patch continues the ongoing rename work, replacing DPValue with
DbgRecord in comments and the names of variables, both members and
fn-local. This is the most labour-intensive part of the rename, as it is
where the most decisions have to be made about whether a given comment
or variable is referring to DPValues (equivalent to debug variable
intrinsics) or DbgRecords (a catch-all for all debug intrinsics); these
decisions are not individually difficult, but comprise a fairly large
amount of text to review.

This patch still largely performs basic string substitutions followed by
clang-format; there are almost* no places where, for example, a comment
has been expanded or modified to reflect the semantic difference between
DPValues and DbgRecords. I don't believe such a change is generally
necessary in LLVM, but it may be useful in the docs, and so I'll be
submitting docs changes as a separate patch.

*In a few places, `dbg.values` was replaced with `debug intrinsics`.
