Rollup merge of #79184 - nanguye2496:nanguye2496/fix_slice_and_str_type_name, r=varkor 
Stop adding '*' at the end of slice and str typenames for MSVC case

When computing debug info for MSVC debuggers, Rust compiler emits C++ style type names for compatibility with .natvis visualizers. All Ref types are treated as equivalences of C++ pointers in this process, and, as a result, their type names end with a '\*'. Since Slice and Str are treated as Ref by the compiler, their type names also end with a '\*'. This causes the .natvis engine for WinDbg fails to display data of Slice and Str objects. We addressed this problem simply by removing the '*' at the end of type names for Slice and Str types.

Debug info in WinDbg before the fix:

This change has also been tested with debuggers for Visual Studio, VS Code C++ and VS Code LLDB to make sure that it does not affect the behavior of other kinds of debugger.
