Allow .S files in C++ Starlark cc_common.compile.

.S files are (typically handwritten) assembly files that require
preprocessing, compared to their lower-capital .s counterparts that can
be compiled directly into object files.

Native cc_library rules already allow .S files in srcs [1]. However, the
Starlark cc_common.compile srcs argument doesn't accept them. This
change adds .S files to the list of valid srcs for cc_common.compile.

This is required for building AOSP, as there are handwritten source files in
Android's libc with the .S extension [2] that will be compiled through
Starlark C++ rules, e.g. directly into .o files.
