Restore ToCDouble compatibility with leading spaces/+ and hex

Browse source 
The previous ToCDouble() function accepted leading spaces, a starting +
sign, and hex strings. std::from_chars() does not accept spaces or +,
and requires a special flag to convert hex strings, so handle this
manually to preserve the old behaviour of this function.

This is similar to the changes done for ToCULong() in #24022.

Closes #24089.
