don't inherit allowed deprecation from parent modules
...
Inheriting allow-deprecation from parent modules doesn't make too much
sense, so instead make them default to disallow unless otherwise
specified. This allows build system to avoid redundant
`-fno-allow-deprecated` args.
This makes the generated CLIs smaller, and makes zig1.wasm update not
needed.
Also represented `is_root` differently (moved to field of graph).

ubsan: don't create ubsan in every static lib by default
...
Problem here is if zig is asked to create multiple static libraries, it
will build the runtime multiple times and then they will conflict.
Instead we want to build the runtime exactly once.

Compilation: always import ubsan if a ZCU exists
...
Unlike `compiler-rt`, `ubsan` uses the standard library quite a lot.
Using a similar approach to how `compiler-rt` is handled today, where it's
compiled into its own object and then linked would be sub-optimal as we'd
be introducing a lot of code bloat.
This approach always "imports" `ubsan` if the ZCU, if it exists. If it doesn't
such as the case where we're compiling only C code, then we have no choice other
than to compile it down to an object and link. There's still a tiny optimization
we can do in that case, which is when compiling to a static library, there's no
need to construct an archive with a single object. We'd only go back and parse out
ubsan from the archive later in the pipeline. So we compile it to an object instead
and link that to the static library.
TLDR;
- `zig build-exe foo.c` -> build `libubsan.a` and links
- `zig build-obj foo.c` -> doesn't build anything, just emits references to ubsan runtime
- `zig build-lib foo.c -static` -> build `ubsan.o` and link it
- `zig build-exe foo.zig bar.c` -> import `ubsan-rt` into the ZCU
- `zig build-obj foo.zig bar.c` -> import `ubsan-rt` into the ZCU
- `zig build-lib foo.zig bar.c` -> import `ubsan-rt` into the ZCU
