ci: fold bespoke GPU.yml into CI.yml [GPU] group; canonical group Project.tomls

Replace the root Tests.yml + bespoke GPU.yml with a single canonical CI.yml
(matching the OrdinaryDiffEq umbrella layout):

- CI.yml carries the version matrix for the root base groups
  (Core/SymbolicIndexingInterface/Downstream/NoPre on [lts, 1, pre], NoPre
  excluded on pre) via SciML/.github tests.yml@v1.
- The GPU tests become a dep-adding group on the self-hosted GPU runner: a
  dedicated CI.yml job passes group=GPU and
  runner=[self-hosted, Linux, X64, gpu] to tests.yml@v1 (which sets
  GROUP=GPU; runtests.jl then activates test/gpu and runs the GPU
  safetestsets). This reproduces the former GPU.yml (same runner labels,
  60-min timeout, src,ext coverage) so GPU.yml is deleted.

- Give the dep-adding root group Project.tomls the canonical
  [sources] = {path=../..} (+ sibling sublib paths) plus the package and Test
  deps so they resolve on Julia >= 1.11 against the PR-branch code:
  - test/gpu: add Adapt/ArrayInterface/RecursiveArrayTools/Test/Zygote +
    [sources] for the root and RecursiveArrayToolsArrayPartitionAnyAll.
  - test/nopre: add RecursiveArrayTools + [sources].
  - test/downstream: add Test + [sources] for root and
    RecursiveArrayToolsShorthandConstructors.
