Update the Windows packaging script.

As discussed here:
https://discourse.llvm.org/t/build-llvm-release-bat-script-options

These are the changes in this patch:

Add a function to parse command line arguments: `parse_args`.

The format for the arguments is:
Boolean: `--option`
Value: `--option=value`

Command line usage example:
`my-batch-file.bat --build --type=release`

It will create 2 variables:
`build` with the value `true`
`type` with the value `release`

Usage:

  set "build="
  set "type="
  REM Parse arguments.
  call :parse_args %*
  if defined build (
    ...
  )
  if %type%=='release' (
    ...
  )
