Introduce an abstraction layer for reporting diagnostics, so as to avoid
directly using the native GCC interfaces such as "error_at",
"warning_at", "open_quote", "close_quote", etc. The new interfaces have
the same look and feel as the GCC equivalents, but make calls into
back-end functions to allow the back end to select the proper final
reporting routine.

substring_loc::get_location currently fails for the final terminator
character in a STRING_CST from the C frontend, so that format_warning_va
falls back to using the location of the string as a whole.
This patch tweaks things [1] so that we use the final closing quote
as the location of the terminator character, as requested in
PR preprocessor/77672.
[1] specifically, cpp_interpret_string_1.
