  Log Message:
  -----------
  [lldb][dwarf] Compute fully qualified names on simplified template names with DWARFTypePrinter (#112811)

This is the second half of
https://github.com/llvm/llvm-project/pull/90008.

Essentially, it replaces the work of resolving template types when we
just need the qualified names with walking the DIE tree using
`DWARFTypePrinter`.

### Result
For an internal target, the time spent on `expr *this` for the first
time reduced from 28 secs to 17 secs.
