[FE] Support analyzable files throughout all 'KtPsiFactory' API

Before, the only way of getting analyzable elements was to create an
analyzable file by using 'createAnalyzableFile()'. So made all utilities
available in 'KtPsiFactory' useless as they delegate to 'createFile()'
that always set the 'doNotAnalyze' flag.

The new behavior is to pass the 'analysisContext' instead if it is
passed to the 'KtPsiFactory' constructor.

The newly appeared API is going to be used in the Kotlin's UAST
implementation.
