Auto-generate .vhdl_ls.toml for VS Code VHDL LS from OSVVM build flow

[BekdoucheAmine]

Description

This PR introduces a TCL-based solution to automatically generate the VS Code VHDL Language Server configuration file (.vhdl_ls.toml) directly from the OSVVM build process.

Implementation

• Added Scripts/VendorScripts_GenerateVhdlLsToml.tcl
• Added GenerateVhdlLsToml procedure for VHDL LS integration in Scripts/StartUp.tcl
• Reuses the OSVVM vendor script mechanism (vendor_analyze_vhdl)
• Hooks into the standard build flow
• Collects analyzed VHDL files per library
• Generates .vhdl_ls.toml grouped by [libraries.<name>] in the user workspace
• Non-intrusive: does not change existing build behavior

[libraries.osvvm]
files = [
    '<OSVVM_ROOT>/osvvm/IfElsePkg.vhd',
    '<OSVVM_ROOT>/osvvm/OsvvmTypesPkg.vhd',
    ... 
    '<OSVVM_ROOT>/osvvm/OsvvmContext.vhd',
  ]
  
[libraries.OSVVM_Common]
files = [
    '<OSVVM_ROOT>/Common/src/ModelParametersPtPkg.vhd',
    ... 
    '<OSVVM_ROOT>/Common/src/OsvvmCommonContext.vhd',
  ]
  
[libraries.osvvm_uart]
Files = [
    '<OSVVM_ROOT>/UART/src/UartTbPkg.vhd',
    ... 
    '<OSVVM_ROOT>/UART/src/UartRx.vhd',
  ]
  
# ... remaining libraries omitted for brevity ...

Usage

source ../OsvvmLibraries/Scripts/StartUp.tcl
GenerateVhdlLsToml ../OsvvmLibraries

This will:

• Run the OSVVM build flow
• Capture analyzed VHDL files per library
• Generate/update .vhdl_ls.toml
• Restore the default OSVVM script behavior

Notes

• Paths are currently normalized; relative-path handling can be refined later depending on workspace conventions.
• The feature follows the approach discussed in Issue Auto-generate VHDL LS .toml library configuration from OSVVM .pro files #72 and builds on the existing VendorScripts_CompileList.tcl methodology.

Hi @JimLewis I've implemented what we discussed in Issue #72. I'll look into VHDL LS and check if relative paths can be used within the .toml file and I'll get back to you.

A variable can be added to the GenerateVhdlLsToml to indicate where the .toml file should be stored.
