refactor(common): Make ahash optional

[dsherret]

Description:

This adds the ability to not include ahash with swc_common, which caused some issues for me compiling dprint-plugin-typescript to Wasm because of:

   Compiling ahash v0.8.3
   Compiling getrandom v0.2.10
error: the wasm*-unknown-unknown targets are not supported by default, you may need to enable the "js" feature. For more information see: https://docs.rs/getrandom/#webassembly-support

(I can't enable the JS feature because it's running the wasm file in Wasmer and also I don't support Wasi in dprint plugins)

BREAKING CHANGE:

This removes swc_common's "perf" feature and makes it the default, then adds an ahash feature instead. An alternative would be to make the ahash dep optional and part of the default features, then do default-features = false in the downstream crates (I think, but I'm not sure), but I figure most people will be using the perf default anyway? I'm not sure what's preferable.
