* Remove usage of `CompilationStrategy` from `Config` This commit removes the public API usage of the internal `CompilationStrategy` enumeration from the `Config` type in the `wasmtime` crate. To do this the `enum` was copied locally into the crate and renamed `Strategy`. The high-level description of this change is: * The `Config::strategy` method now takes a locally-defined `Strategy` enumeration instead of an internal type. * The contents of `Strategy` are always the same, not relying on Cargo features to indicate which variants are present. This avoids unnecessary downstream `#[cfg]`. * A `lightbeam` feature was added to the `wasmtime` crate itself to lightbeam compilation support. * The `Config::strategy` method is now fallible. It returns a runtime error if support for the selected strategy wasn't compiled in. * The `Strategy` enum is listed as `#[non_exhaustive]` so we can safely add variants over time to it. This reduces the public crate dependencies of the `wasmtime` crate itself, removing the need to reach into internal crates even more! cc #708 * Fix fuzz targets * Update nightly used to build releases * Run rustfmt
