Silence unecessary `!Sized` binding error

When gathering locals, we introduce a `Sized` obligation for each
binding in the pattern. *After* doing so, we typecheck the init
expression. If this has a type failure, we store `{type error}`, for
both the expression and the pattern. But later we store an inference
variable for the pattern.

We now avoid any override of an existing type on a hir node when they've
already been marked as `{type error}`, and on E0277, when it comes from
`VariableType` we silence the error in support of the type error.

Fix #117846.
