Subject: [PATCH 1/2] Format: add AlignAfterOpenBracketOptions
Introduce new options to allow for control of AlwaysBreak and
BlockIndent selectively for If conditional statements (as currently
supported), other conditional statements (for/while/switch), and
other statements.
Fixes #67738.
Fixes #79176.
Fixes #80123.
