Use MurmurHash3 when native hashing function is not available

Adds a pure JS implementation of a string hashing function. We do not
use it for security or obfuscation purposes, only to create compact
hashes. So we prioritize speed over collision avoidance. For example, we
use this to hash the component key path used by useFormState for
MPA-style submissions. See facebook#27397 for details.

In environments where built-in hashing functions are available, we
prefer those instead. Like Node's crypto module, or Bun.hash.
Unfortunately this does not include the web standard crypto API because
those methods are all async. For our purposes, we need it to be sync
because the cost of context switching is too high to be worth it.

The most popular hashing algorithm that meets these requirements in the
JS ecosystem is MurmurHash3, and almost all implementations I could find
used some version of the implementation by Gary Court. So that's the
one I've used.

In the future we should try to migrate these to native calls whenever
possible. It's especially unfortunate that the Edge build doesn't use
a native implementation, because that's the one used by newer frameworks
like Next.js.
