fix(linter): speed up inferred plugin node processing

[meeroslav]

This PR improves the createNodes function of eslint's inferred plugin by making two pragmatic choices:

• reusing the ESLint between config file's runs instead of recreating the new one every time
• skipping ignored files checks for projects that already have eslint config file

Results of benchmarks on customer's repo:

Without ESLint plugin

• create-project-graph-async - avg. 11739.1326225 -> 11 seconds

With current ESLint plugin

• create-project-graph-async - avg. 98005.0965135 -> 98 seconds

With modified ESLint plugin

• create-project-graph-async - avg. 13225.073817 -> 13 seconds
  • (@nx/eslint/plugin:createNodes - 2206.96497, 16.69%)
