Slava Pestov d579a76581 Sema: Break request cycle when building TypeRefinementContexts ...

This fixes a recent regression introduced in the changes to make
TRC construction lazier in b33a71d64f.

Calling VarDecl::hasInitialValue() can ask for attached property
wrappers, which can trigger macro expansion. However, macro
expansion can result in TRC construction, causing a cycle.

Instead, just always build a lazy TRC for the initializer. It
might not be needed, but it's safest to not ask anything of the
VarDecl at all.

Fixes rdar://118452948.
