fix EmbeddedResource access on net472

[9rnsr]

There are three embedded resouces in NPOI.

• functionMetadata.txt and font_metrics.properties in NPOI project
• presetTableStyles.xml in NPOI.OOXML project

In previous, thee resource files on net472 has inconsistent settings against NET Core.

• NPOI.csproj:
  The two files had shorthand LogicalNames.

     <ItemGroup>
       <EmbeddedResource Include="Resources\functionMetadata.txt">
         <LogicalName>functionMetadata.txt</LogicalName>
       </EmbeddedResource>
       <EmbeddedResource Include="Resources\font_metrics.properties">
         <LogicalName>font_metrics.properties</LogicalName>
       </EmbeddedResource>
     </ItemGroup>
  

• NPOI.OOXML.csproj:
  presetTableStyles.xml had been properly regeistered in NPOI.OOXML.Core.csproj, but not in NPOI.OOXML.csproj as EmbeddedResource, so it had been already broken in net472.

After we migrate SDK style csproj in #1037, the default LogicalName which has assembly name + relative path in project is given to each embedded resourecs. But, the shorthand names were still used for net472 by conditional compilation, so the runtime resource loading has been failing.

This fix will significantly increase passed test numbers in net472.
