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.

 Vendors like Altera, Lattice and Xilinx have their own simulation libraries,

 There are also popular simulation and verification libraries like [OSVVM][osvvm]
 and [UVVM][uvvm], which can be pre-compile, too.
 
 The compilation scripts are writen in the shell languages: PowerShell for Windows

 ---------------------------------------------------------------------
-### Script Configuration
-
-The vendor library compile scripts need to know where the used / latest vendor
-tool chain is installed. Therefore, the script implement a default installation
-directory search as well as environment variable checks. If a vendor tool could
-not be detected or the script choses the wrong vendor library source directory,
-then it's possible to provide the path via `--source` or `-Source`.
 
-The generated output is stored relative to the current working directory. The
-scripts create a sub-directory for each vendor. The default output directory can
-be overwritten by the parameter `--output` or `-Output`.
-
-To compile all source files with GHDL, the simulator executable is searched in
-`PATH`. The found default GHDL executable can be overwritten by setting the
-environment variable `GHDL` or by passing the parameter `--ghdl` or `-GHDL` to
-the scripts.
-
-If the vendor library compilation is used very often, we recommend to configure
-these parameters in `config.sh` or `config.psm1`, so the command line can be
-shortened to the essential parts.

-installed vendor tools to the appropriate directory to your tool's installation

-
-`config.sh`:

-
-#### For Windows: `config.psm1`
-
-Please open the `config.psm1` file and set the dictionary entries for the
-installed vendor tools to the appropriate directory to your tool's installation
-folder. Use an empty string `""` for not installed tools.
