Restore manganis optimizations (#3195)

* Create a crate for constant serialization of config structs for manganis
* use SerializeConst for the image asset builder
* switch to a declarative macro for assets
* add serializable options for each asset type
* implement the new manganis macro
* optimize assets in the CLI
* Fix assets with dioxus formattable
* reduce fuzzing test limits
* use the new syntax in examples
* fix avif support
* Fix manganis doc tests
* cache asset optimization
* Split out asset and bundled asset
* make hash pointer width independent
* Fix manganis macro docs
* add constvec::is_empty method to fix clippy lint
* remove nasm feature
* simplify test_rsplit_once test so typos passes
* revert example change from clippy fix
* always accept unix paths
* fix windows path seperator
* fix folder asset hash
* Optimize assets in a blocking task
* Fix asset options docs
* Document Asset and BundledAsset
* simplify the linker macro a bit
* add more docs to AssetParser expansion
* add image format helpers
* Split by  both unix and windows path separators and take the smallest one
