It's confusing and redundant to use `When true` and `when false` in descriptions for a CLI arguments because specifying false/true is redundant in a command line argument flag and in most cases users will not do it.
Example:
`--foo=true` is the same as `--foo`
`--foo=false` is the same as `--no-foo`
Currently when using `ivy-ngcc` it will print out a warning
```
Failed to read entry point info from //node_modules/@schematics/angular/workspace/files/package.json with error SyntaxError: Unexpected token < in JSON at position 1121.
```
Fixes#13378
At the moment some schematics contain this options for instance the `guard`, `component` etc.. But some others don't such as `module`
Fixes#12894 and Fixes#6272
This aligns options that do the same thing:
1) `skipSpecs` and `spec` has been deprecated in favor of `skipTests`.
2) `styleext` has been deprecated in favor of `style` since the latest is two words.
Fixes#12784
