This commit removes a TLS lookup of the store information whenever a
trap is created. This was previously done to lookup information in the
module registry, but nowadays there's a global registry which has all
the equivalent information as well. This commit moves around some code
in the module registry and then uses this global map when creating
traps.This is not motivated by performance, and likely regresses performance
slightly since it involves taking a global lock now. That being said the
perf of creating aTrapis generally not super consequential, so this
is seen as ok.The goal of this commit is to lessen Wasmtime's reliance on TLS for
store-based information. I'm hoping to lessen this even more with the
changes for bytecodealliance/rfcs#11, where acquiring a store via TLS is
going to be much more difficult if not possible any more.<!--
