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

+
+## How it works
+
+`const-serialize` relies heavily on well defined layouts for the types you want to serialize. The serialization format is the linear sequence of unaligned bytes stored in the order of the fields, items or variants of the type. Numbers are stored in little endian order.
+
+In order to support complex nested types, serialization is done using a trait. Since functions in traits cannot be const, `const-serialize` uses a macro to generate constant associated items that describe the memory layout of the type. That layout is then used to read all of the bytes in the type into the serialized buffer.
+
+The deserialization is done in a similar way, but the layout is used to write the bytes from the serialized buffer into the type.
+
+The rust [nomicon](https://doc.rust-lang.org/nomicon/data.html) defines the memory layout of different types. It is used as a reference for the layout of the types implemented in `const-serialize`.
+
+## Limitations
+
+- Only constant sized types are supported. This means that you can't serialize a type like `Vec<T>`. These types are difficult to create in const contexts in general
+- Only types with a well defined memory layout are supported (see https://github.com/rust-lang/rfcs/pull/3727 and https://onevariable.com/blog/pods-from-scratch). `repr(Rust)` enums don't have a well defined layout, so they are not supported. `repr(C, u8)` enums can be used instead
+- Const rust does not support mutable references or points, so this crate leans heavily on function data structures for data processing.

+# Manganis
+
+The Manganis allows you to submit assets to any build tool that supports collecting assets. It makes it easy to self-host assets that are distributed throughout your libraries. Manganis also handles optimizing, converting, and fetching assets.
+
+If you defined this in a component library:
+
+```rust
+use manganis::{Asset, asset};
+const AVIF_ASSET: Asset = manganis::asset!("/assets/image.png");
+```
+
+AVIF_ASSET will be set to a new file name that will be served by some CLI. That file can be collected by any package that depends on the component library.
+
+```rust
+use manganis::{ImageFormat, ImageAssetOptions, Asset, asset, ImageSize};
+// You can collect arbitrary files. Absolute paths are resolved relative to the package root
+const _: Asset = asset!("/assets/script.js");
+
+// You can collect images which will be automatically optimized
+pub const PNG_ASSET: Asset =
+    asset!("/assets/image.png");
+// Resize the image at compile time to make the assets smaller
+pub const RESIZED_PNG_ASSET: Asset =
+    asset!("/assets/image.png", ImageAssetOptions::new().with_size(ImageSize::Manual { width: 52, height: 52 }));
+// Or convert the image at compile time to a web friendly format
+pub const AVIF_ASSET: Asset = asset!("/assets/image.png", ImageAssetOptions::new().with_format(ImageFormat::Avif));
+```
+
+## Adding Support to Your CLI
+
+To add support for your CLI, you need to integrate with the [manganis_cli_support](https://github.com/DioxusLabs/manganis/tree/main/cli-support) crate. This crate provides utilities to collect assets that integrate with the Manganis macro. It makes it easy to integrate an asset collection and optimization system into a build tool.
