One: Compiler FE : Speed up CI build and test time

[mhs4670go]

CI builds and tests nncc every PR. But it makes us spends too much time building and testing. So, it is better to do a long test(e.g. tf2tfliteV2 test takes like 5 minutes), not every PR, just periodically.

There are a few options I think.

1. Reduce build time
   We can make a white list which is created by gathering frequently used(need to discusstion) or necessary to releases.
   then,
   every PR build - build with white list
   push build - build all module

2. Reduce test time
   We can add command to ./nncc test like below.
   ./nncc test -E ".*_remote_test|tf2tfliteV2_.*"
   then,
   every PR build - test with above command
   push build - test all module

Second option looks good to me but first option looks a little bit optional.

Please give your opinion:)

I'm not sure, but you may skip build tf2tfliteV2 with -DBUILD_COMPILER_TF2TFLITEV2=OFF:

What is the distinction between PR build and push build?

[mhs4670go]

@s-barannikov it is build type. former builds with debug, latter builds with release. Well, the person in charge said that server pool will be added to cover more jobs soon. So, as of now, there will be no change.
