Enso tests can be run with filter from cmdline

[Akirathan]

Closes #8998

Pull Request Description

Simplify the Test.Suite.run_with_filter to accept a single filter parameter that searches for all the groups and specs that matches that filter. This filter can be a simple text provided from the command line.

Important notes

• Pending groups are now printed at the end of the run
• Test.Suite.run_with_filter is simplified to accept a single filter parameter that is either Text or Nothing. See the docs.
  • Passing a filter from the command line is therefore straightforward, it is treated as a regex.
• For convenience, I have left all the main methods in all the test sources. I have just refactored them to accept the filter argument from the command line.
  • For example, to run only a single spec from Vector_Spec.enso, invoke enso --run test/Base_Tests/src/Data/Vector_Spec.enso "should allow vector creation with a programmatic constructor"
• Majority of the PR is a regex replace of ^main = for main filter=Nothing = and of suite.run_with_filter for suite.run_with_filter filter.
