feature request: inlay gas estimation for functions

[levx-me]

I think Remix's feature of showing inlay gas estimation for each function is really cool

Could it be implemented in intellij-solidity as well?

(You can see 594 gas, 616 gas on the right)

Hi @levx-me!
I've implemented gas estimation hints under this PR.
However, it works when using the hardhat framework only.
Do you use any framework in your project?

I use foundry these days

It's a great news that it's supported at least for hardhat
