[Relax][Bugfix] Annotate ComputePrimValue output as host function

[Lunderberg]

The ComputePrimValue transform is used to compute the value of symbolic expressions that may appear within a Relax function. For example, to compute a boolean condition used for a relax::If node. These functions are used for small host-side computations, prior to launching a device kernel.

This commit updates ComputePrimValue to annotate the generated PrimFunc with tir::attr::kIsHostFunc. This annotation is required for correct behavior in tvm.dlight.ApplyDefaultSchedule, to avoid erroneous scheduling of this function for the GPU, and for tir::transform::BindTarget, to ensure that the function is compiled for execution on the host.

due to recent ci restart, likely we need to close and re create another pr for the ci to get retriggerd

[Lunderberg]

Thank you for looking into the CI failures, and I'll resubmit as a new PR. Looks like #17022 and #17023 have the similar CI failure, as they were all submitted while the CI was down.
