This commit adds initial (gated) support for the multi-memory wasm
proposal. This was actually quite easy since almost all of wasmtime
already expected multi-memory to be implemented one day. The only real
substantive change is the `memory.copy` intrinsic changes, which now
accounts for the source/destination memories possibly being different.

* Disable static memory under QEMU on CI
This commit disables the usage of "static" memory on CI and instead
forces all memories to be "dynamic" meaning that they reserve much
smaller chunks of memory. This causes the QEMU process's memory to
drastically drop (10GiB -> 600MiB) and should allow us to keep enabling
tests without hitting the OOM killer on CI.

* Move most wasmtime tests into one test suite
This commit moves most wasmtime tests into a single test suite which
gets compiled into one executable instead of having lots of test
executables. The goal here is to reduce disk space on CI, and this
should be achieved by having fewer executables which means fewer copies
of `libwasmtime.rlib` linked across binaries on the system. More
importantly though this means that DWARF debug information should only
be in one executable rather than duplicated across many.
* Share more build caches
Globally set `RUSTFLAGS` to `-Dwarnings` instead of individually so all
build steps share the same value.
* Allow some dead code in cranelift-codegen
Prevents having to fix all warnings for all possible feature
combinations, only the main ones which come up.
* Update some debug file paths
