[Build] Add flag to build-win.ps1 that allows to build Release.static target

[lucianopa-msft]

We are building using this build-win.ps1 but we wanted to be able to use the "Release.static" target. But currently there is no such option to that.
We currently have our own workaround:

function Repair-BuildScript {
    param (
        [string]$RepoPath
    )
    # Modify build-win.ps1 to use Release.static target instead of Release.vc14x.MT-sqlite.
    # This is unfortunate, but the build script does not take parameters for this setting, if we specify libTypes to lib it forces us for MT-sqlite
    $filePath = "$RepoPath\build-win.ps1"
    $oldText = '".vc14x.MT-sqlite"'
    $newText = '".static"'

    # Read, replace, and save the file
    (Get-Content $filePath) -replace $oldText, $newText | Set-Content $filePath
}

Which is fine, but sending this PR aiming to allow that option as well. Default remains true to not modify current behavior.

Because static libs are only supported for x86/x64, should a check be added here to do the guard?
