Shinonn 86405fb507 Fix ICE by rejecting const blocks in patterns during AST lowering
This fixes the ICE reported by rejecting `const` blocks in
pattern position during AST lowering.

Previously, `ExprKind::ConstBlock` could reach HIR as `PatExprKind::ConstBlock`,
allowing invalid patterns to be type-checked and triggering an ICE.
This patch removes the lowering path for const blocks in patterns
and emits a proper diagnostic instead.

A new UI test is added to ensure the compiler reports a regular error
and to prevent regressions.
