Alex Rickabaugh 718d7fe5fe fix(ivy): properly parenthesize ternary expressions when emitted (#34221)
Previously, ternary expressions were emitted as:

condExpr ? trueCase : falseCase

However, this causes problems when ternary operations are nested. In
particular, a template expression of the form:

a?.b ? c : d

would have compiled to:

a == null ? null : a.b ? c : d

The ternary operator is right-associative, so that expression is interpreted
as:

a == null ? null : (a.b ? c : d)

when in reality left-associativity is desired in this particular instance:

(a == null ? null : a.b) ? c : d

This commit adds a check in the expression translator to detect such
left-associative usages of ternaries and to enforce such associativity with
parentheses when necessary.

A test is also added for the template type-checking expression translator,
to ensure it correctly produces right-associative expressions for ternaries
in the user's template.

Fixes #34087
