…es for constructors

Fix false positive for when a function specifier (e.g. `inline`, `protected`) is provided
Fix false positive for when constructor ends on the same line a MemInitList does, but on a different line from said list's start
Fix ownership assignment of open parentheses
Use search instead of match for some cases
Fix typo & misc refactoring

Fixes `: a({0}), b{"c", d}` etc. F/Ps
Consumes and updates state of MemInitList so we get to the curly braces before _ConsumeEnd() does
Splits ending token searches/checks into `_ConsumeEnd()`
Requires starting index to initialize `_WrapInfo`s
Renames _WrappedInfo to _WrapInfo since Wrapped is not a noun

…ned consumption

Fix the direction in which we find braces
Fix bug where consumption doesn't happen due to return None without returning the consumed line
Refactored consumption functions to have the loop themselves
Change tests to account for that
