clang-format: Fix bug with conflicting BreakBeforeBinaryOperations and AlignAfterOpenBracket

Fix for the formatting options combination of
BreakBeforeBinaryOperators: All, AlignAfterOpenBracket: AlwaysBreak not
handling long templates correctly. This patch allows a break after an
opening left parenthesis, TemplateOpener, or bracket when both options
are enabled.

Patch by Daphne Pfister, thank you!

Fixes llvm.org/PR30304.
