Motiejus Jakštys ece6f69054 astgen: fix builtinCall rvalue, operand coercion, and result type handling ...

- Move rvalue calls inside builtinCall (all builtins now call rvalue
  internally, matching upstream) and remove outer rvalue wrap from
  call site
- Add rlResultTypeForCast that errors when no result type is available,
  used by @bitCast, @intCast, @truncate, @ptrCast, @enumFromInt
- Fix @import to compute res_ty from result location instead of
  hardcoding ZIR_REF_NONE
- Fix @embedFile to evaluate operand with coerced_ty=slice_const_u8_type
- Fix @cInclude/simpleCBuiltin to check c_import scope and use
  comptimeExpr with coerced_ty=slice_const_u8_type
- Fix @cImport to pass actual block_result to ensure_result_used instead
  of hardcoded ZIR_REF_VOID_VALUE

Not fixed: Issue 14 (ptrCast nested pointer cast collapsing) — upstream
routes @ptrCast through a dedicated ptrCast() function that walks nested
pointer cast builtins. Currently uses simple typeCast path only.
