On Linux default use_static_cpp to disabled

[dsnopek]

Fixes #1876

This implements option nr 1, which I guess I'm leaning to, because it's the least surprising. This option has only existed for a short time, so changing the default shouldn't be too big of a deal

I dont know how to propose changes inline in the code, but in the linux.cmake:22

set(STATIC_CPP "$<BOOL:${GODOTCPP_USE_STATIC_CPP}>")

can be changed to:

    set(STATIC_CPP "$<AND:$<BOOL:${GODOTCPP_USE_STATIC_CPP}>,$<BOOL:${GODOTCPP_USE_HOT_RELOAD}>>")

99.9% sure this is correct, I just cant test on linux atm.

I'm not sure if I'm reading it correctly, but it looks like your change would set STATIC_CPP if both GODOTCPP_USE_STATIC_CPP and GODOTCPP_USE_HOT_RELOAD are enabled?

If so, I don't think that's what we want. If anything, I think we'd want it to only be set if GODOTCPP_USE_HOT_RELOAD is not enabled, but that's what #1877 does and I think that's a little problematic. The goal of this PR was just to change the default of use_static_cpp and GODOTCPP_USE_STATIC_CPP to disabled.
