Well first of all why would anyone nowadays use targa to store images? It's either uncompressed or only run length encoded and depending on the image content that might not help at all. PNG is a lossless image format with much better compression.

However if you want to use TGA, just use it because it doesn't affect the build size at all. Unity stores the images in an appropriate hardware supported texture format for the given build platform. If the texture is compressed at all and which max resolution it should have can be changed at the import settings of each texture.

Uhm have you missed my second paragraph? If you have you may want to re-read it again, carefully and also read the linked documentation page. Again, the texture source file you put into a Unity project is not the one included in the build. The textures are converted into an appropriate format for the build target platform. So it doesn't matter for the build what the source format is. You can use BMP, PNG, TGA, PSD, ...
