RFR: 8324433: Introduce a way to determine if an expression is evaluated as a constant by the Jit compiler [v2]

[Quan Anh Mai]

> Hi,
> 
> This patch introduces `JitCompiler::isConstantExpression` which can be used to statically determine whether an expression has been constant-folded by the Jit compiler, leading to more constant-folding opportunities. For example, it can be used in `MemorySessionImpl::checkValidStateRaw` to eliminate the lifetime check on global sessions without imposing additional branches on other non-global sessions. This is inspired by `std::is_constant_evaluated` in C++.
