[clang-format] Fix poor spacing in `AlignArrayOfStructures: Left` (#77868)

Fixes llvm/llvm-project#62904

`AlignArrayOfStructures: Left` combined with `SpacesInParentheses: true`
causes the first cell of every row to have 1 additional space.
We were only setting the first cell of the first row to be against the
left brace, now every row will be against the left brace.
