clang-format, Inconsistent formatting with BraceWrapping.AfterControlStatement: MultiLine for single-line and multi-line if conditions

[halcyonx]

Tested with: clang-format version 20.1.3 (https://github.com/llvm/llvm-project 923a5c4)

Using BraceWrapping.AfterControlStatement: MultiLine leads to inconsistent formatting between single-line and multi-line if statements, which creates a visual inconsistency in codebases that use the compact if (cond) {} style.

BraceWrapping:
  AfterControlStatement: MultiLine

if (!flag1) {
	return;
}

if (flag2)
{
	return;
}

If a codebase uses AfterControlStatement: Never and all if statements were consistent, it may still be desirable to apply AfterControlStatement: MultiLine for multi-line if conditions only, while keeping AfterControlStatement: Never for all other cases.
