Enforce safe usage of DiagnosticsEngine::getCustomDiagID()

Replace the last incorrect uses and templatize the function to require a
compile-time constant string preventing further misuse.

The diagnostic formatter expects well-formed input and has undefined behaviour
with arbitrary input or crafted user strings in source files. Accepting user
input would also have caused unbounded generation of new diagnostic IDs which
can be problematic in long-running sessions or language bindings.

This completes the work to fix several incorrect callers that passed user
input or raw messages to the diagnostics engine where a constant format string
was expected.

Give explicit sections for string constants used in NSStrings.

Without them they can be merged with non unnamed_addr constants during LTO.
The resulting constant is not unnamed_addr and goes in a different section,
which causes ld64 to crash.

A testcase that would crash before:

* file1.mm:
void g(id notification) {
[notification valueForKey:@"name"];
}

* file2.cpp:
extern const char js_name_str[] = "name";

* file3.cpp
extern bool JS_GetProperty(const char *name);
extern const char js_name_str[];
bool js_ReportUncaughtException() { JS_GetProperty(js_name_str); }

run

clang file1.mm -o file1.o -c -w -emit-llvm
clang file2.cpp -o file2.o -c -w -emit-llvm
clang file3.cpp -o file3.o -c -w

ld -dylib -o XUL file1.o file2.o file3.o -undefined dynamic_lookup.
