Reworking pre-compile scripts for Windows (#1594)

* Updated pre-compile scripts for OSVVM.

* Reworked script for Vivado.

* Reworked script for ISE.

* Reworked UVVM compile script. Cannot be tested due to missing feature in GHDL see #1593.

* Reworked scripts for Altera, Intel and Lattice.

* Updated module imports.

* Adjusted warnings.

* Read OSVVM package files from compile-order file 'osvvm.pro'.

* Support OSVVM and OSVVMLibraries as source directory.

* Added support for OSVVM models to precompile script.

* First update to the pre-compile scripts documentation.

* Minimized file headers and redundant documentation. Using PowerShell's feature to document files, functions and modules.

* Updated README in precompile scripts directory.

* license: update headers of pyGHDL, scripts/windows, libraries/vendors

* Fixed ForegroundColor and InvocationName.
