[wasm] Move the wasm fuzzer corpus to a different directory

The current test/fuzzer/wasm directory is used for two things:
1) as the corpus directory for clusterfuzz
2) to test in v8 that the fuzzer runs correctly.

With the newly added files from the wasm spec tests this directory grew
quite big and adds unnecessary load on the trybots. Therefore I want to
do the following steps:
1) In this CL for V8: create a new directory for the clusterfuzz corpus
2) In chromium: use the new corpus directory
3) In v8: clean up the old directory to use it on the trybots.
