Update nuspec to place library under nano TFM

[Copilot]

• Updated nanoFramework.System.Security.Cryptography.nuspec to align with develop branch:
  • Wrapped dependency in <group targetFramework=".NETnanoFramework1.0"> element
  • Replaced individual file entries (dll, pdb, pdbx, pe, xml) with a single wildcard entry targeting lib\netnano1.0
  • Updated CoreLibrary version to match develop branch (2.0.0-preview.35)

This section details on the original issue you should resolve

<issue_title>Update nuspec to place library under nano TFM</issue_title>
<issue_description>### Details about task
Most of the nuspec files are not using the correct location to place the files.
Files (DLL, PE, PDBX and XML for IntelliSense) should be placed under "lib\netnano1.0" (currently are being placed under "lib" only.
Also they should declare a dependency group for ".NETnanoFramework1.0" target framework.
At the same time those still naming the various file types should use a wildcard instead (e.g. "...\Release\mscorlib.*).
The correct pattern should be (take this nuspec as sample):
nanoframework/System.Device.Adc@aab7bca

Do not change anything else on the nuspec file.

@copilot this should be done against develop branch

I've updated the branch so the nuspec uses the develop branch's CoreLibrary version (2.0.0-preview.35) — commit 57e4b65. The PR base branch needs to be changed from main to develop (which I'm unable to do directly). Once that's done, the diff will show only the structural changes: dependency group + wildcard file pattern targeting lib\netnano1.0.

@copilot rebase this PR, it should only show diffs in nuspec file
