compilers/d: Add b_ndebug support

D lang compilers have an option -release (or similar) which turns off
asserts, contracts, and other runtime type checking. This patch wires
that up to the b_ndebug flag.

Fixes #7082

sourceset: add all_dependencies() method

'if_true' sources should be built with their dependencies, as
illustrated by test case change.

Ideally, I think we would want only the files with the dependencies to
be built with the flags, but that would probably change the way
sourceset are used.

new module "sourceset" to match source file lists against configuration data

In QEMU a single set of source files is built against many different
configurations in order to generate many executable.  Each executable
includes a different but overlapping subset of the source files; some
of the files are compiled separately for each output, others are
compiled just once.

Using Makefiles, this is achieved with a complicated mechanism involving
a combination of non-recursive and recursive make; Meson can do better,
but because there are hundreds of such conditional rules, it's important
to keep meson.build files brief and easy to follow.  Therefore, this
commit adds a new module to satisfy this use case while preserving
Meson's declarative nature.

Configurations are mapped to a configuration_data object, and a new
"source set" object is used to store all the rules, and then retrieve
the desired set of sources together with their dependencies.

The test case shows how extract_objects can be used to satisfy both
cases, i.e. when the object files are shared across targets and when
they have to be separate.  In the real-world case, a project would use
two source set objects for the two cases and then do
"executable(..., sources: ... , objects: ...)".  The next commit
adds such an example.
