Add methods to enable using formatv syntax in LLDB.
This adds formatv-backed formatting functions in various
places in LLDB such as StreamString, logging, constructing
error messages, etc. A couple of callsites are changed
from Printf style syntax to formatv style syntax to
illustrate its usage. Additionally, a FileSpec formatter
is introduced so that FileSpecs can be formatted natively.
