Move asset hashing into the CLI (#3988)

* Fix deduping assets * hash assets in the linker * fix extracting assets * Fix the hashed asset name * deserialize the asset back from the link section * prevent the read from being inlined * remove some extra logs * Fix liveview routing * Only look for direct dependencies on dioxus features * fix wasm split test * On wasm, create a new object file with the asset information * Fix multiple assets * add a regression test for 3467 * fix image link * fix linker out file * fix linux linker args * add windows linker command * fix linux link args * fix windows target triple * Expose an option to build assets in the linker intercept * Fix the standalone optimizer and document it in the dx help command * include the cli opt version in the hash * fix clippy * fix ssg port * add a safety note to the read_volatile call * move found assets log * fix some merge conflicts * fix build * make most env var for the linker optional * guess the target triple when dx acts as the linker intercept * automatically find the linker for normal builds * use the right linker in wasm mode * fix mac linker * look inside archive files (rlibs) * remove out.txt * fix clippy * fix typo * fix clippy * fix build * fix dx link name in docs * ignore libcompiler_builtins warnings * fix playwright * pass typocheck * fix printing sysroot * Modify final binary * fix wasm assets * remove old link section logic * fix tests * forward manganis export args * fail to evaluate relocatable address * retain all exports in the same pattern as other platforms * Fix adding assets during a wasm hot patch * less nesting and remove logs * fix clippy * log pdb files * read from pdb * print data section contents * print with object * normal windows builds working * fix hot patch windows * clean up logs * fix clippy * clean up assets * use the most recent pdb * fix doc test * fix typo * tiny nits * make bundled a reference instead of a pointer * add helpful comment to impl * match on file format * Fix asset hashing comment --------- Co-authored-by: Jonathan Kelley <jkelleyrtp@gmail.com>
