Subject: [PATCH] x64: only enable VTune dependencies on x86_64 targets (#4533)

As described in #4523, the `ittapi` dependency necessary for Wasmtime's
VTune support does not compile on `aarch64-linux-android`. There are
several incompatible parts here: though `ittapi` supports all OS
combinations that Wasmtime does and builds on all CPU targets, VTune is
not primarily intended for aarch64 profiling and `linux-android` is not
a high priority platform for the library. We could conditionally depend
on `ittapi` for Wasmtime's supported OS combinations, but I think a
better answer is to limit it to x86_64 targets, since this more clearly
shows why the `ittapi`/VTune support is present and also fixes #4523.
