Initialize schemas array with explicit size
Currently `update_schemas.py` generates a schema list definition like
redfish-core/include/schemas.hpp:
```
constexpr std::array schemas {
"AccountService",
"ActionInfo",
...
"OpenBMCAccountService",
};
```
However, if the number of schemas is more than the clang's default
max size, CI may fail.
The default is `-fbracket-depth=256`.
```

```
To avoid the failure, we can set the size explicitly like
```
constexpr std::array<std::string_view,277> schemas {
"AccountService",
...
```
Tested:
1) Remove `include_list` so that all possible schemas are to be used
2) Run with the fixed `scripts/update_schemas.py`
3) Compiles successfully
