Refactor tile, transpose, and resize to use indexing view (#274)

* refactor to_string

* refactor tile, transpose, resize to use indexing view

* fix sycl eval

* various utl fixes, add has_dst_size & has_src_size metafunction

* update tsets

* fix cuda build

* try to fix arduino ci

* try to fix arduino ci

* try to fix gcc-index ci

* try to fix bounded_size inference for indexing view

* temporarily disable some eval test on no-stl tests

* try to fix hipsycl ci

* skip resize tests on hipsycl-cuda

* try to fix platformio ci

* temporarily disable arduino-platformio manip & constexpr ci
