4ba6d02ab6 Revert "Workaround for fontconfig returning junk in all but the lowest eight bits for FC_INDEX" 
This reverts commit d2c21ee297.

Apparently fontconfig overloads the top 16 bits as "instance index"
which is some kind of index for variable fonts? Who knows. fontconfig is
a natural disaster.

Fixes #7361

d9ccbcd0ce Font fallback: Fix the font used to render a character sometimes dependent on the order in which characters appear on screen 
We ameliorate the performance hit by storing a hash table mapping cell
text to the loaded fallback font index so that lookups for previously
seen text are still fast.

ccc370e1c4 Dont initialize FontConfig when importing fast_data_types 
This reduces the import time for fast_data_types by 12ms on my machine.
FontConfig initialization is very slow and it is only needed by the
main kitty program, however fast_data_types is imported in kittens and
remote control as well, where FontConfig is useless.

8dea5b3e3e Reduce data sent to GPU per draw by 30% 
Split up the Cell structure into a CPUCell and a GPUCell. Only the
GPUCell part needs to be sent to the GPU. Should make kitty use even
less system resources and make a performance difference on systems where
the GPU bandwidth is constrained.

Also allows adding more CPU only data in the future without affecting
GPU bandwidth. For example, hyperlinks or more combining characters.
