This patch enables Ion by default as the optimising compiler for wasm on AArch64, and disables Cranelift. Cranelift is still available if the build is configured with --enable-cranelift. In that case, *only* Cranelift is available. There are no configuration flags to enable both Ion and Cranelift simultaneously. This mostly reverts the Phase 0 and Phase 1 patches that are bug 1678097 D102420 and D101867 respectively. The command line option --wasm-force-ion has been removed. With this patch in place, users of the shell should specify `--wasm-compiler=optimizing` to get an optimising wasm compiler. Which one is provided depends on the configuration options as described above. `--wasm-compiler=cranelift` and `--wasm-compiler=ion` are now only accepted when the relevant compiler has been enabled, and so neither is a "safe" way to request an optimising tier. For that reason, test directories that previously requested also-with-Ion-please by stating `test-also=--wasm-compiler=ion;` in their `directives.txt` file, have been changed to use `test-also=--wasm-compiler=optimizing;`. In places where the JSContextOptions are set, the non-selected compiler (Ion or CL) is explicitly set to `false` (eg, `.setWasmIon(false)`). This may be overly conservative, but seems wise given that it's not immediately obvious what the previous value of that flag is, and given the recent difficulties with incorrect option propagation/handling (eg, bug 1697560).
