make ResourceLimiter operate on Store data; add hooks for entering and exiting native code (#2952)

Browse Source 
* wasmtime_runtime: move ResourceLimiter defaults into this crate

In preparation of changing wasmtime::ResourceLimiter to be a re-export
of this definition, because translating between two traits was causing
problems elsewhere.

* wasmtime: make ResourceLimiter a re-export of wasmtime_runtime::ResourceLimiter

* refactor Store internals to support ResourceLimiter as part of store's data

* add hooks for entering and exiting native code to Store

* wasmtime-wast, fuzz: changes to adapt ResourceLimiter API

* fix tests

* wrap calls into wasm with entering/exiting exit hooks as well

* the most trivial test found a bug, lets write some more

* store: mark some methods as #[inline] on Store, StoreInner, StoreInnerMost

* improve tests for the entering/exiting native hooks
