We rename `AnalyzerOptions` to `AnalysisFileOptions`, and change it's
comment from "`analyzer` analysis options constants." to avoid anyone
thinking it is specifying options for the `analyzer` section.
Additionally I privatize some of the static values that are only
present for validation - they are not meant to be used outside of
`options.dart`: `AnalyzerSection._trueOrFalse`,
`AnalyzerSection._options`, `AnalyzerSection._strongModeOptions`,
`AnalyzerSection._languageOptions`, `LinterSection._options`.
I also rename `_TopLevelAnalyzerOptionsValidator` to
`_AnalyzerTopLevelOptionsValidator` to align with
`_LinterTopLevelOptionsValidator`.
