PSScriptAnalyzer fixes by category (#4261)

- Fix PSScriptAnalyzer warnings of type PSAvoidUsingCmdletAliases for 'ForEach-Object' (alias is '%' or 'foreach')
- Fix PSScriptAnalyzer warnings of type PSAvoidUsingCmdletAliases for 'Where-Object' (alias is '?' or 'where')
- Fix PSScriptAnalyzer warnings of type PSAvoidUsingCmdletAliases for 'Select-Object' (alias is 'select')
- Fix PSScriptAnalyzer warnings of type PSPossibleIncorrectComparisonWithNull. Essentially, $null has to be on the left-hand side when using it for comparison.
- A Test in ParameterBinding.Tests.ps1 needed adapting as this test used to rely on the wrong null comparison
- Replace a subset of tests of kind '($object -eq $null) | Should Be $true' with '$object | Should Be $null'
