Split executable semantics fuzzer into cc_binary and cc_test

Browse Source 
This is a workaround for #1208, allowing to remove manual tag to allow building and testing fuzzer code during precommits and in bazel test ...

Tested:
bazel test -k ...
bazel build -c opt executable_semantics/fuzzing:executable_semantics_fuzzer
bazel-bin/executable_semantics/fuzzing/executable_semantics_fuzzer
