Suppress duplicate librares linker warning of new macOS linker

Fixes #24167

XCode 15 introduced a new linker which warns on duplicate libraries being
linked. To disable this warning, we pass -Wl,-no_warn_duplicate_libraries as
suggested by Brad King in CMake issue #25297.

This flag isn't necessarily available to other linkers on darwin, so we must
only configure it into the CC linker arguments if valid.

testsuite: Encoding test witnesses recent iconv bug is fragile

A regression in the new iconv() distributed with XCode 15 and MacOS
Sonoma causes the test 'encoding004' to fail in the CP936 roundrip.

We mark this test as fragile until this is fixed upstream (rather than
broken, since previous versions of iconv pass the test)

See #24161

testsuite: Update to LC_ALL=C no longer being ignored in darwin

MacOS seems to have fixed an issue where it used to ignore the variable
`LC_ALL` in program invocations and default to using Unicode.

Since the behaviour seems to be fixed to account for the locale
variable, we mark tests that were previously broken in spite of it as
fragile (since they now pass in recent macOS distributions)

See #24161

darwin: Fix single_module is obsolete warning

In XCode 15's linker, -single_module is the default and otherwise
passing it as a flag results in a warning being raised:

    ld: warning: -single_module is obsolete

This patch fixes this warning by, at configure time, determining whether
the linker supports -single_module (which is likely false for all
non-darwin linkers, and true for darwin linkers in previous versions of
macOS), and using that information at runtime to decide to pass or not
the flag in the invocation.

Fixes #24168

testsuite: Skip MultiLayerModulesTH_Make on darwin

The recent toolchain upgrade on darwin machines resulted in the
MultiLayerModulesTH_Make test metrics varying too much from the
baseline, ultimately blocking the CI pipelines.

This commit skips the test on darwin to temporarily avoid failures due
to the environment change in the runners. However, the metrics
divergence is being investigated still (tracked in #24177)

configure: check target (not build) understands -no_compact_unwind

Previously, we were branching on whether the build system was darwin to
shortcut this check, but we really want to branch on whether the target
system (which is what we are configuring ld_prog for) is darwin.

JS: Fix missing variable declarations

The JStg IR update was missing some local variable declarations
that were present earlier, causing global variables to be used
implicitly (or an error in JavaScript strict mode).

This adds the local variable declarations again.

users-guide: Fix links to libraries from the users-guide.

The unit-ids generated in c1a3ecde720b3bddc2c8616daaa06ee324e602ab include the
package name, so we don't need to explicitly add it to the links.

Fixes #24151

EPA: splitLHsForAllTyInvis does not return ann

We did not use the annotations returned from splitLHsForAllTyInvis, so
do not return them.
