Import web-platform-tests/wasm/jsapi. Some of tests are failing just because imported wpt tests are old.
They are fixed in the upstream. When upgrading wpt tests, we can mark them PASS.

Source/JavaScriptCore:
This patch fixes miscellaneous issues in our Wasm JS API implementation to improve WPT score.
I picked trivial ones in this patch to make this easily reviewable.
1. Remove WebAssemblyPrototype. It does not exist in the spec. Merging WebAssemblyPrototype into JSWebAssembly.
2. Fix various attributes. It does not match to the usual JSC builtin's convention. But this change
is correct because they are changed to be matched against WebIDL definition, and WebAssembly implementation
follows WebIDL. In the future, we could move WebCore WebIDL things into WTF layer and even use (or leverage
some of utility functions) in our WebAssembly JS API implementation.
3. Fix how we interpret "present" in WebAssembly spec. This does not mean [[HasProperty]] result. It follows to
WebIDL spec, and it means that [[Get]] result is not undefined.
4. Add argument count check to Module.customSections, which is required because the method is defined in WebIDL.
5. Fix toNonWrappingUint32 to match it to WebIDL's conversion rule.
