hardhat compile and test contracts

[wighawag]

Feedback

Currently it seems that hardhat compile do not compile test contract

but it compiles them when running test unless --no-compile is specified in which case it won't compile them

this means that if you want to control compilation and use --no-compile the only way to compile the test contract is to use

hardhat compile src/**/*.sol (assuming contract source is src)

but this behaviot depends on the shell and can cause problem where this command is specified in npm/package.json scripts

it would be great to have an option to compile all contracts

I guess a simple way to solve this is for hardhat compile to support globs

We need some design work here. Maybe two apis in the build system: one for tests and other for standard contracts. Then we need to decide what the default for compile is.

Perhaps subtasks, e.g. npx hardhat compile tests
