Sized enums still aren't supported

[cD1rtX3]

Type: Bug

Step 0: Set your "C Standard" to at least c23 (I have it on gnu23).

Step 1: Declare a sized enum:

enum: uint32_t {
    foo = 0xDEADBEEF,
    bar = 0x12345678,
    baz
}

Step 2: Distinct lack of profit.

Even with #7471 being closed, I still have this issue with Intellisense, though the code compiles fine.

@cD1rtX3 This is not implemented by our our parser yet -- you can track the progress in the EDG column at https://en.cppreference.com/w/c/compiler_support/23 row "Enumerations with fixed underlying types".

The root c23 issue is at #10696, but we can use this issue to track this specific feature.
