[Format] Invert nestingAndIndentLevel pair in WhitespaceManager used for

alignments

Indent should be compared before nesting level to determine if a token
is on the same scope as the one we align with. Because it was inverted,
clang-format sometimes tried to align tokens with tokens from outer
scopes, causing the assert(Shift >= 0) to fire.

This fixes bug #33507. Patch by Beren Minor, thank you!
