Web Replay: code generator shouldn't complain about enums without a storage type if they are in an enclosing scope
https://bugs.webkit.org/show_bug.cgi?id=137084

Reviewed by Joseph Pecoraro.

In order to generate encode/decode method declarations without pulling in lots of headers,
the generator must forward declare enums (for enum classes or enums with explicit sizes).

Change the generator to not require an explicit size if an enum is declared inside a struct
or class definition. In that case, it must pull in headers since scoped enums can't be
forward declared.

This patch also fixes some chained if-statements that should be if-else statements.

Test: updated replay/scripts/tests/generate-enum-encoding-helpers.json to cover the new case.
