Fix bundling/path errors, sidecar support, iOS/Android simulator support, asset hotreload fixes, serverfn hotrelad, native tailwind support

[jkelleyrtp]

Attempt fixes for:

• Git version of dioxus fails to load collected assets using the Desktop template #2526
• [Desktop] Hot reloading does not work in the "tailwind" sample #2386
• live reload doesn't work when just modifying the css file #2379
• Manganis CSS Hot Reloading #2429
• dx serve output is not entirely clear #2176
• For bundling, desktop apps should canonicalize assets automatically. #232
• Per platform dist directory #2692
• dioxus full stack hotreload fails with custom target dir #2509
• dx serve prints "Failed to parse file: No such file or directory" and starts rebuild sometime on static string change (Neovim) #2312
• Routing errors and the use of Manganis if the site is located in a subdirectory of the domain, as on GitHub Pages. #2093
• prepare_html panic, in main branch #2762
• Desktop: Error setting the App Icon #2344 (because we're joining from cwd instead of the asset dir)
• Permissions issues when bundling app image after recursive dir fixes #2487
• dioxus-cli does not proxy websocket connections #2155
• Change default location of WebView2 folder on Windows #2304

Misc cleanup:

• fix all cache thrashing
• get mobile + fullstack working
• change fullstack to be a binary yes/no thing
• helpful warnings when running fullstack w/o server functions
• refactor CLI staging to include bundles (and thus, bundled hotreloading)
• lay groundwork for Ability To Build/Bundle Multiple Platforms At Once #2754
• adds run command (like serve without the TUI)

Currently cutting out:

• parse env!() as std::env::var or meta tags in html
• drop dep count on cli-config
• dioxus-hotreload should be dioxus-devtools

Pending to be cut out:

• change "hotreload" crate to "devtools"
• adds http-server command
• adds doctor command for tooling
• rename "hotreload" feature to "devtools"

Cut out of this PR (and merged):

• move hotreload context into core-types
• move bubbles fn into core-types
• new core-types crate
• new isrg crate Split out isrg from ssr and reorient build graph to make interpreter build 2x faster #2969
• remove oidc example (wasn't compiling) Extract some simple cleanups from 2779 #2966
• rsx-hotreload is a dedicated crate instead of a feature flag Improve compile times by splitting out rsx-hotreload from rsx #2971
• hoist project examples up to example-projects folder Chore: hoist example projects for discoverability #2959
• Clean cruft from web crate Chore: remove old cruft in web crate #2957
• remove old/unused deps
• cut down deps and compile times by 50% (other half, manganis, still wip)

Cut out and pending merge:

• eval is behind document and not a "free" function
• move Title/Stylesheet/Link behind document module (ie document::Title {}
• completely change launch function to not warn us with deprecation lints
• router uses document navigation abstraction
• remove channel Evalutor (todo: move this to sdk? separate crate?)
• new dioxus-document crate (pulled out of html)
• remove websys from html (via newtypes in web)
• remove js gen from dioxus-html

Punted:

• How to handle Tauri sidecars and allowing externalBin to be called ? #1454
• Support automated bundling of appimage #451
• Ability To Build/Bundle Multiple Platforms At Once #2754
• Document dioxus.toml configuration values (bundling, various private/undocumented fields) docsite#334
• Clean up the prelude #2718

We have many "dioxus rebuilds too frequently errors" and mostly it's due to cache thrashing because of env!() in build scripts and rustflags being incompatible.
