Better Image handling (#2665)

* enhance asset mgmt

- invoke ico directly
- invoke ico only at shortcut creation
- remove "ConvertTo-Icon" Function file

- removed image from xaml
- added stackpanel to xaml
- added functions to create viewbox with image
- added logic to add image via code to xaml & customdialog
- changed title color for customdialog

- remove webinvokes for assets from main.ps1

TODO: convert images into bitmap base64 string & add them directly into invoke-WinUtiltaskbaritem.ps1

* improve viewboxfunction

- add logo + checkmark + warning
- add params
- render on param "render"
- custom dialog logo function call fix
- main logo function call fix
- update winutiltaskbaritem to use new images

* fix sizing

- warning & checkmark sizing fix
- remove unneded comments

* fixes

- remove unneeded redundancy of "$canvas = New-Object Windows.Controls.Canvas"
- adjust empty lines
- use LimeGreen instead of Green

* fix layouting

* fixes

- use correct ctt blue color #0567ff
- remove unneeded comments
- rename Logoview to assets

* performance improvement

instead of rendering the image another time on each item switch, it caches it at the start and uses the render afterwards

* redo gray part of winutil logo

* correct gray shade

* fix coloring

* ise ico if available

-        .DESCRIPTION
-        This function will convert BMP, GIF, EXIF, JPG, PNG and TIFF to ICO file
-
-        .PARAMETER bitmapPath
-        The file path to bitmap image to make '.ico' file out of.
-        Supported file types according to Microsoft Documentation is the following:
-        BMP, GIF, EXIF, JPG, PNG and TIFF.
-
-        .PARAMETER iconPath
-        The file path to write the new '.ico' resource.
-
-        .PARAMETER overrideIconFile
-        An optional boolean Parameter that makes the function overrides
-        the Icon File Path if the file exists. Defaults to $true.
-
-        .EXAMPLE
-        try {
-            ConvertTo-Icon -bitmapPath "$env:TEMP\cttlogo.png" -iconPath "$env:TEMP\cttlogo.ico"
-        } catch [System.IO.FileNotFoundException] {
-            # Handle the thrown exception here...
-        }
-
-        This Example makes a '.ico' file at "$env:TEMP\cttlogo.ico" File Path using the bitmap file
-        found in "$env:TEMP\cttlogo.png", the function overrides the '.ico' File if it's found.
-        this function will throw a FileNotFound Exception at the event of not finding the provided bitmap File Path.
-
-        .EXAMPLE
-        try {
-            ConvertTo-Icon "$env:TEMP\cttlogo.png" "$env:TEMP\cttlogo.ico"
-        } catch [System.IO.FileNotFoundException] {
-            # Handle the thrown exception here...
-        }
-
-        This Example is the same as Example 1, but uses Positional Parameters instead.
-
-        .EXAMPLE
-        if (Test-Path "$env:TEMP\cttlogo.png") {
-            ConvertTo-Icon -bitmapPath "$env:TEMP\cttlogo.png" -iconPath "$env:TEMP\cttlogo.ico"
-        }
-
-        This Example is same as Example 1, but checks if the bitmap File exists before calling 'ConvertTo-Icon' Function.
-        This's the recommended way of using this function, as it doesn't require any try-catch blocks.
-
-        .EXAMPLE
-        try {
-            ConvertTo-Icon -bitmapPath "$env:TEMP\cttlogo.png" -iconPath "$env:TEMP\cttlogo.ico" -overrideIconFile $false
-        } catch [System.IO.FileNotFoundException] {
-            # Handle the thrown exception here...
-        }
-
-        This Example make use of '-overrideIconFile' Optional Parameter, the default for this parameter is $true.
-        By doing '-overrideIconFile $false', the 'ConvertTo-Icon' function will raise an exception that needs to be catched throw a 'catch' Code Block,
-        otherwise it'll crash the running PowerShell instance/process.
