Change base image to emscripten/emsdk

See merge request !12

temporarily disable sqlite since it tries to use `--experimental-wasm-memory64` flag which is not supported in node v24

- use node v8 canary binary until node v24 is out.

- use VTK's CI scripts to download missing build tools
 and build dependencies.

gitlab-ci: remove `dependencies` from jobs

See merge request !11

Historically, `needs` specifies the jobs which need to complete
successfully and `dependencies` specifies the jobs which provide
artifacts which should be used. Modern GitLab discourages using both as
`needs` now supports an `artifacts` key to say "depend on but do not use
artifacts", so remove `dependencies` and use `needs:artifacts` where
necessary.

Bump dockcross/web-wasm:20240812-60fa1b0

See merge request vtk/vtk-wasm-sdk!10

- allocating large memory can lead to oom in some runners.

- libproj thirdparty in VTK uses `-Werror` and called
 `check_c_source_compiles` to test for `PTHREAD_MUTEX_RECURSIVE`
- in release build for wasm64 arch, clang emitted a warning
  `-Wlimited-postlink-optimizations` only in 64 bit
  which was treated as an error (because of the `-Werror`)
- we negate that warning in the dockerfile.

configure: enable webgpu

See merge request !9

Use cmake script from VTK to download node in `build` stage

See merge request !8

- no need to download cmake because the dockcross/web-wasm container already has cmake and ninja.

Revert "Disable octree module"

See merge request !7

This reverts commit 682c757f

Run publish stage only after merged on the default branch

See merge request !6

- octree fails to compile with new emscripten 3.1.60

- for emcc 3.1.60

- adds a new `test` stage in CI
- publish stage now depends on tests, so that faulty images are not pushed to dockerhub

- Describe vtk-wasm-sdk

- will be fixed by vtk!10898

- The image will be tagged with date and git describe as usual.
- Additionally, instead of using the latest tag, it is possible to
  specify the tag through environment var `VTK_IMAGE_TAG`

This reverts commit 17325a0d.

When logging is enabled, static initialization order bugs occur
within vtkPolyData from VTK::CommonDataModel and vtkObjectBase from
VTK::CommonCore
