Update docstrings to reference ModelingToolkit's own documentation

Instead of only referencing generic solver documentation, the docstrings now
point to ModelingToolkit's own problem building documentation as the primary
reference, with solver-specific docs as secondary references.

This provides better context for MTK-specific features and workflows while
still pointing users to the underlying solver documentation for advanced options.

All problem constructor docstrings now reference:
1. ModelingToolkit.jl problem building documentation (primary)
2. Relevant solver documentation (secondary)
