Improvements for contract implementation selector

[k1rill-fedoseev]

Contract implementation selector on the source code section https://eth.blockscout.com/address/0x1231DEB6f5749EF6cE6943a275A1D3E7486F4EaE?tab=contract_code

should allow to copy implementation address and allow to open implementation in the separate tab, like it's done on the read/write proxy tabs

Also, implementation selector should apply the chosen option not only to the source code section, but to the remaining sections as well (ABI, constructor args, bytecode, compiler settings, etc..), currently all these section display info from the main proxy contract regardless of the option chosen.
