ResultOption Updates

[1eyewonder]

Proposed Changes

ResultOption functions

• Updated functions to use generic constraints
• Updated parameters to use InlineIfLambda attributes where applicable

ResultOption CE

• Updated to have similar functionality as rest of CEs in order to provide users the most bang for their buck

Unit Tests

• Created unit tests for the CE
• I goofed on the previous few PRs by not adding the unit tests in FsToolkit.ErrorHandling.Tests to the Main.fs file. I tried making it so all tests are picked up in the assembly but as the comment that was previously there, the top level test list needs to be there for dotnet test to work ☹️
