xpack: `set_bindir()` only affects the .html file and not the .wasm and .js file in a wasm package

[mhcerri]

Xmake Version

3.0.1+HEAD.3350cc5

Operating System Version and Architecture

Ubuntu 22.04

Describe Bug

When generating a zip archive with a web build if I use set_bindir(".") only the html file is moved and the wasm and js files are still left in the bin/ directory.

Expected Behavior

The js and wasm files should be placed at the same location as the html file.

Project Configuration

Example:

xpack configuration:

includes("@builtin/xpack")
xpack("myapp", function ()
    add_targets("myapp")

    -- Type of archive
    if is_plat("linux") then
      set_formats("targz")
    else
      set_formats("zip")
    end

    -- File name
    set_basename("myapp-$(version)_$(plat)_$(arch)")

    -- Set the archive structure
    set_prefixdir("myapp-$(version)")
    set_bindir(".")
end)

Generatated zip:

$ unzip -l ./build/xpack/myapp/myapp-1.0.0_wasm_wasm32.zip
Archive:  ./build/xpack/myapp/myapp-1.0.0_wasm_wasm32.zip

The bin directory is hardcoded here. https://github.com/xmake-io/xmake/commit/cdd5062919821da123cd84d5dbb3cb07cd889ee9

installfiles cannot distinguish between bin and lib files. Therefore it cannot use the global set_bindir .
