When dumping AST, the JSON format can be requested in two ways: `-ast-dump=json` and `-ast-dump-all=json`. Both of those command line options control `FrontendOptions::ASTDumpFormat`.

This patch deduplicates the options by introducing `-ast-dump-format`, removes the `_EQ` variants of `-ast-dump` and `-ast-dump-all`, and simplifies option parsing/generation.
