[parser] Fix issue 52365 about parsing parenthesised functions followed by >> etc

Record parsing is generally done by accepting what comes after as
something that can follow a record type.
To support something like `List<List<(int, int)>>` we have to accept
`>>` after a record type.
When parsing something like `(whatever here) >> 42;` we thus say that
it's a record --- even if the stuff inside is a recovered type. We
inherit the `recovered` mark, but will say we're a record type.

This CL fixes parsing this by returning that it's _not_ a record type
when seing the `>>` (an a few others) if what's inside is recovered.

This _might_ mean worse recovery in some situations but fixes parsing
valid code such as `(() => print("hello")) >> 42;`.
