Fix formatting of lambda introducers with initializers.
Most of the work was already done when we introduced a look-behind based
lambda introducer detection.
This patch finishes the transition by completely relying on the simple
lambda introducer detection and simply recursing into normal
brace-parsing code to parse until the end of the introducer.
This fixes initializers in lambdas, including nested lambdas.
Before:
auto a = [b = [c = 42]{}]{};
auto b = [c = &i + 23]{};
After:
auto a = [b = [c = 42] {}] {};
auto b = [c = &i + 23] {};
