test cases: add abigail_reader tests converted from info_tests

Create XML files from all "info" test cases to test abigail reader.

XML files were generated using `abidw` (version `2.1.0`) on compiled source
files from `info_tests`. For example, commands would look like:

```
clang-17 -std=c17 -g -fstandalone-debug --target=riscv64-linux-gnu \
    -c simple_array.c -o simple_array.c.o
abidw --no-architecture --no-corpus-path --type-id-style hash \
    --no-comp-dir-path --no-show-locs simple_array.c.o \
    > simple_array.c.raw_xml
```

STG expectation files were generated by running command like:

`stg --abi simple_array.c.xml --output expected/simple_array_c.abi_stg`
