Now the main span focuses on the erroneous not-a-function callee,
while showing the entire call expression is relegated to a secondary
span. In the case where the erroneous callee is itself a call, we
point out the definition, and, if the call expression spans multiple
lines, tentatively suggest a semicolon (because we suspect that the
"outer" call is actually supposed to be a tuple).
The new `bug!` assertion is, in fact, safe (`confirm_builtin_call` is
only called by `check_call`, which is only called with a first arg of
kind `ExprKind::Call` in `check_expr_kind`).
Resolves #51055.

* When encountering EOF, point at the last opening brace that does not
have the same indentation level as its close delimiter.
* When encountering the wrong type of close delimiter, point at the
likely correct open delimiter to give a better idea of what went
wrong.

This commit is the result of (first) searching via ripgrep (0.8.1 -SIMD -AVX):
rg -l dynamically-sized-types-and-sized
and then replacing all relevant occurrences via:
find src/{libcore,test/ui} -type f -print0 | xargs -0 sed -i.bak \
s/dynamically-sized-types-and-sized/dynamically-sized-types-and-the-sized-trait/g
find src/{libcore,test/ui} -type f -name '*.bak' -print0 | xargs -0 rm
(Note: Tested on on macOS 10.13 (BSD). `sed -i.bak` should work on Linux
(GNU sed) as well, but not tested.)
