tree: Enable warning for fallthrough in switch statements
The EC code has generally been good about adding comments about
intentional fallthrough in switch statements, but there were a few cases
without comments (e.g., https://crrev.com/c/3949622). Enabling
-Wimplicit-fallthrough generates a compiler warning if the fallthrough
is not annotated with __attribute__((fallthrough)). For convenience, we
add a "__fallthrough" macro for this attribute.
See https://clang.llvm.org/docs/AttributeReference.html#fallthrough and
https://gcc.gnu.org/onlinedocs/gcc/Statement-Attributes.html.
