[JSC] Remove BytecodeCacheVersion.h
​https://bugs.webkit.org/show_bug.cgi?id=204760

Reviewed by Mark Lam.

Having that as a phony make target causes a lot of unnecessary rebuilds. That was a workaround
the fact that we only need a new cache version when we rebuild CachedTypes.cpp, but there was
no straightforward way to get the current timestamp as an integer at that point. Instead, we now
just use a constexpr function that hashes TIMESTAMP.
