We regressed binary size when we switch Darwin to use LLD, because
Darwin LD64 does ICF by default. Turn on ICF for host binaries to regain
the binary size savings (saves some space for Linux as well).

* Disable bugprone-unchecked-optional-access because it
crashed with some Android files.
* Allow misc-const-correctness and bugprone-assignment-in-if-condition
as warnings, not to stop build as errors.
Disable them in the global default check list.
* Allow/show clang deprecated* and array-parameter warnings for the NEXT version.

Some code compiles with -Werror, which makes it very hard to mark
anything as deprecated without breaking the build. This option
will ensure that we can still mark things as deprecated without
breaking such code. Among other things, this will allow us to
undo a local change to protobuf which disables deprecation
warnings.

Some build targets pulls cflags from build/soong but has its own choice
of compiler version. This causes errors for due to unknown warning
options. This allows them to suppress such checks.

The staging compiler update sometimes needs additional cflags to build, but those flags may not be recognised by the current compiler. Add a
new `llvmNextExtraCommonGlobalCflags` section and only append those
flags when LLVM_NEXT is set.

This flag has never done anything for ld.lld, since it has this behavior
by default (and actually can't turn it off either). It's now being
removed as a valid flag from ld.lld, so it's time for Android to drop
the unnecessary flags. See https://reviews.llvm.org/D118942.

noOverrideExternalGlobalCflags is a new set of flags intended to be
added at the end of the command line for 3rd party projects like
external/, hardware/, vendor/, and more. Our previous flags for external
projects occur way too early on the command line, leading to issues with
use for suppressing diagnostics. Note that support for this variable in
build/make is currently unimplemented, as there are no projects that
would depend on it. It could be added in the future, if it turns out to
be useful.
This change initially applies `-Wno-unused-but-set-variable` and
`-Wno-unused-but-set-parameter` to external projects because these
upstream projects aren't easily fixed, and the risk of actual bugs is
low.
