[core] Resolved GCC13 build warning regarding std::copy of a bool.

[maxsharabayko]

The GCC 13 compiler produces a warning complaining that the length used for std::copy is out of bounds of an integer (or any other 1-byte type).
The source of this complaint was that the length was set in the getOptDefault, instead of a direct sizeof value. Even though the length returned for a Boolean is anyway determined via sizeof(Type) called from a template function, it is probably not that safe anyway.
Therefore just assert (in a debug build configuration) that the size returned is similar to the sizeof call used in the importOption function.

Fixes #3064.

The assertion is not always true. In particular, it is not holding for the Duration type on Travis Linux jobs (see this one).

Default length is 8 (sizeof std::chrono::duration), the length from getOptDefault is 4 (RD(-1) -> w_optlen = fillValue((pw_optval), w_optlen, -1);).

A similar bug with:

• SRTO_PAYLOADSIZE: getOptDefault returns 4, the value in config is size_t (8 bytes)
• SRTO_PBKEYLEN: getOptDefault returns 4, the value in config is size_t (8 bytes)

[ethouris]

We need to have a defined data types assigned for every such option, and all required fields should accord.

For these two options, the data type holding it should be exactly the same as the one expected by the user to supply when calling srt_set/getsockflag.
