Fix variable shadowing in nested map/list deserialization code generation

[pulimsr]

Description of changes: Fixed variable shadowing in the code generator template for nested map/list deserialization. The template now appends recursion depth to variable names when processing nested structures, preventing MSVC C4456 warnings that are treated as errors.

Changes to ModelInternalMapOrListJsonDeserializer.vm:

• Append recursion depth to variable names when depth > 1
• Update internal collection names to include recursion depth for both map values and list members
• Ensures unique variable names at each nesting level (e.g., conditionJsonMap, condition2JsonMap, condition3JsonList)
