Subject: [clang-format] Add support for absl nullability macros (#130346)

Add support for formatting w/ absl nullability macros
(https://github.com/abseil/abseil-cpp/blob/c52afac4f87ef76e6293b84874e5126a62be1f15/absl/base/nullability.h#L237).
Example at https://godbolt.org/z/PYv19M1Gj
input:
```
std::vector<int* _Nonnull> x;
std::vector<int* absl_nonnull> y;
```

orig output:
```
std::vector<int* _Nonnull> x;
std::vector<int * absl_nonnull> y;
```

new output:
```
std::vector<int* _Nonnull> x;
std::vector<int* absl_nonnull> y;
```
