Copy Business Foundation Test Libraries app to symbols folder in New-…

…BcCompilerFolder (#3710)

I probably found a missing app handling in `New-BcCompilerFolder`. When
populating the cache folder, "Business Foundation Test Libraries" is not
being copied to the symbols folder. Therefore, apps that have a
dependency on it will not compile due to missing symbols.

Example:
```
$artifactURL = "https://bcartifacts-exdbf9fwegejdqak.b02.azurefd.net/sandbox/25.0.23364.25278/de"
$compilerFolder = New-BcCompilerFolder -artifactUrl $artifactURL -includeAL
$symbolsFolder = Join-Path $compilerFolder "symbols"

$filePattern = "Microsoft_Business Foundation Test Libraries*.app"
$fileCheck = Get-ChildItem -Path $symbolsFolder -Filter $filePattern
if ($fileCheck) {
    Write-Host "File exists in the folder: $symbolsFolder" # result with fix
} else {
    Write-Host "File does NOT exist in the folder: $symbolsFolder"  # result without the fix
}
```
