UVS support in picker (phase 1)

[yichun-uv]

Summary

Add UVS simulator support to picker (Phase 1), enabling users to generate and build UVS-based testbenches alongside existing Verilator and VCS backends.

Changes

• Simulator registration — Register uvs as a supported simulator in the parser map (src/parser/parser_map.cpp)
• Codegen support — Add UVS-specific include directory flags (-include) and waveform dumping support ($usdbDumpfile / $usdbDumpvars) in the code generator (src/codegen/lib.cpp, src/codegen/sv.cpp)
• Build system — Add three new cmake templates for UVS-based C++, Python, and library builds, handling UVS/UVD detection, DPI library compilation, and linking (template/cpp/cmake/uvs.cmake, template/lib/cmake/uvs.cmake, template/python/cmake/uvs.cmake)
• DUT runtime — Add DutUvsBase class implementing the UVS simulator interface (clock timing, step/run, finish) and wire it into DutUnifiedBase (template/lib/dut_base.cpp, template/lib/dut_base.hpp)
• Example integration — Add reset initialization to example testbenches and a release-uvs.sh build script for the DualPortStackCb example

Notes

• Waveform, checkpoint, restore, and coverage operations are stubbed as unsupported in this phase
• Requires UVS_HOME and UVD_HOME environment variables at build time

LGTM, should we consider adding/modify some documents to help users better understand the precautions when using UVS in the Picker? Of course, there is no problem in adding them after the subsequent stage is completed.
