  [Flang] Compute elemental character MIN/MAX result length in HLFIR (#189464)

This patch fixes lowering of elemental character MIN/MAX in HLFIR.

Previously, these cases could hit a lowering-time TODO
`ElementalIntrinsicCallBuilder::computeDynamicCharacterResultLength` and
abort. This change computes the character result length as the maximum
length of the present actual arguments, allowing valid elemental
character MIN/MAX calls to lower successfully.

Added regression coverage for elemental character MIN/MAX, including
differing-length arguments.
