Fix property expander when comparing between non-numeric and numeric properties

[JaynieBai]

Fixes #10583

Context

Can't evaluate

    <PropertyGroup>
      <Foo>Foo</Foo>

      <!-- This has to be numeric. -->
      <Bar>1234</Bar>

      <!-- This is a workaround. -->
      <Good>$([System.String]::Equals($(Foo), $(Bar)))</Good>

      <!-- This works on .NET 7 but on 8 it doesn't. -->
      <Bad>$(Foo.Equals($(Bar)))</Bad>
    </PropertyGroup>

Changes Made

Use the double.TryParse instead of the convert method

Testing

Add the test cases in the test method Medley()
