asbind20: add package (#7596)

* New package: asbind20

* Update xmake.lua

* I think angelscript should store `PACKAGE_VERSION` in generated `ConfigVersion`

* Pass version from package portfile to port buildsystem

* fixup

* Exported target namespace starts with capital letter, but XMake auto-generated CMakeConfig defines it as angelscript::angelscript

* Inherit on_check for i386 macosx mingw from angelscript package

* fixup

* just test

* retry

* retry

* retry

* re

* re

* try another way

* Update xmake.lua

* Store checks in one `on_check`

* Fix typo
