Merge bitcoin/bitcoin#24077: util: Make base_uint::GetHex() and base_uint::SetHex() not depend on uint256
a4f4f89815 Replace uint256 specific implementations of base_uint::GetHex() and base_uint::SetHex() with proper ones that don't depend on uint256 and replace template methods instantiations of base_uint with template class instantiation (Samer Afach)

Pull request description:

  The current implementations of `SetHex()` and `GetHex()` in `base_uint` use `arith_uint256`'s implementations. Which means, any attempt to create anything other than `arith_uint256` (say `arith_uint512`) and using any of these functions (which is what I needed in my application) will just not work and will cause compilation errors (besides the immediate linking errors due to templates being in source files instantiated only for 256) because there's no viable conversion from `arith_uint256` and any of the other possible types. Besides that these function will yield wrong results even if the conversion is possible depending on the size. This is fixed in this PR.

Pavlos Antoniou e5c616888b Fix instantiation and array accesses in class base_uint<BITS>
The implementation of base_uint::operator++(int) and base_uint::operator--(int) is now safer.
Array pn is accessed via index i after bounds checking has been performed on the index, rather than before.
The logic of the while loops has also been made more clear.

A compile time assertion has been added in the class constructors to ensure that BITS is a positive multiple of 32.

Wladimir J. van der Laan 6bd0dc2a84 arith_uint256: remove initialization from byte vector
Remove initialization from vector (as this is only used in the tests).

Also implement SetHex and GetHex in terms of uint256, to avoid
duplicate code as well as avoid endianness issues (as they
work in term of bytes).

Wladimir J. van der Laan 30007fda76 Remove now-unused methods from arith_uint256 and base_uint
- Methods that access the guts of arith_uint256 are removed,
as these are incompatible between endians. Use uint256 instead

- Serialization is no longer needed as arith_uint256's are never
read or written

- GetHash is never used on arith_uint256
