Internal error when struct param is used outside struct

**Describe the bug**
When there is parametrized struct and its parameter's name is used somewhere outside the struct, then the internal error occurs. In such case I would expect some error that tells the definition was not found.

**To Reproduce**
Steps to reproduce the behavior:
1. Write following code
`foo.x`
```rust
struct Data {
a: uN[PARAM],
}

proc Foo {
config () {()}
init { }

next (state: ()) {
let test_val = Data { a: uN[PARAM]:1 };
}
}
```
2. Build DSLX library target
```bazel
xls_dslx_library(
name = "foo_dslx",
srcs = ["foo.x"],
deps = [],
)
```
```bash
bazel build //:foo_dslx
```
3. Observe internal error:
```none
ERROR: /.../google-xls/BUILD:76:17: Parsing and type checking DSLX source files of target foo_dslx failed: (Exit 255): bash
failed: error executing ParseAndTypeCheckDSLXSourceFile command (from target //:foo_dslx) /bin/bash -c ... (remaining 1 argument skipped)

**Expected behavior**
I would expect following error:
```none

0009:
0010: next (state: ()) {
0011: let test_val = Data { a: uN[PARAM]:1 };

0013: }

```

**Environment (this can be helpful for troubleshooting):**
- OS: Arch Linux x86_64
- Kernel version: 6.11.6-arch1-1
- XLS hash: fc06ae6cd2e9a23675afcaa43ecccc6cb7a1aa39

**Additional context**
When the parameter is removed from the struct, the internal error is not returned and instead there is the same error as in "Expected behavior".
