Nullkiller AI will now prefer giving its scout heroes faster units to
optimize their movement points on next turns.
Unit selection logic:
- AI prefers to give 'weak' units that won't affect army strength of main
hero. Unit is considered 'weak' if its level below 4 or if its AI value
is below 1% of total army strength. So AI can give high-tier unit to
scout, but only if main hero already has massive army.
- Within weak units, if hero is moving on terrain with penalty, AI will
always prefer units that are native to this terrain. So on snow AI will
always prefer unit from Tower even if its speed is lower than unit from
another faction.
- Within remaining candidates, AI will prefer unit that will give higher
movement points limit. This also means that in case of H3 rules, all
units with 11+ speed will be viewed as equally good
- If there are multiple units with same speed, AI will prefer unit with
lowest AI value
* Fix warnings/errors on MSVC
1. update googletest to tag release-1.11.0 to make googletest and
googlemock compile on MSVC2022.
2. set gtest_force_shared_crt to ON in test cmake project to make tests
compile on MSVC.
3. add /wd4251 and /wd4275 to MSVC compile flags to ignore DLL related
warnings for class exports.
4. fix some other warnings and errors while compiling on MSVC2022.
