normal lines and PP directives.

Handling PP directives differently can be desired, like in #161848.
Changing the default is not an option, there are tests for exactly the
current behaviour.

Replace the `AlwaysBreak` and `BlockIndent` suboptions of
`AlignAfterOpenBracket` with new style options `BreakAfterOpenBracket*`
and `BreakBeforeCloseBracket*` for `*` in `BracedList` for braced list
initializers, `if` for if conditional statements, `Loop` for loop
control statements (for/while), `Switch` for switch statements, and
`Function` for function calls/declarations/definitions.

Deprecates `AlwaysBreak` and `BlockIndent`.

The code did not match the documentation about Cpp11BracedListStyle.
Changed handling of comments after opening braces, which are supposedly
function call like to behave exactly like their parenthesis counter
part.

Fixes #36459.

    return;
}
```

Before this patch, the `ObjCMethodExpr` type was assigned to many kinds
of tokens. The rule for allowing breaking the line before the colon on
line TokenAnnotator.cpp:6289 was intended for method declarations and
calls. It matched the parenthesis following `@selector` by mistake. To
fix the problem, this patch adds a new type for `@selector`. Most of the
special things in the code related to the old type is intended for other
constructs. So most of the code related to the old type is not changed
in this patch.

And apply throughout the code base.

This in effect reverts 05fb8408de23c3ccb6125b6886742177755bd757 and
7e1a88b9d1431e263258e3ff0f729c1fdce342d3, the latter of which
erroneously changed the behavior of formatting `ObjC` header files when
both the default and `ObjC` styles were absent. Now the previous
behavior of treating that as an error is restored.

Fixes #158704

The test cases are adapted from #131605.
