Add get/set_prefixed_denom APIs + apply some improvements

[Farhad-Shabani]

Closes: #502

---

Description

Following the review of the similar context on IBC-go and the revisiting codes that were related to the PrefixedDenom, I have also applied and included some tweaks in this PR as follows. Did so for the sake of time-saving, I hope you'll like them ;)

Added missing APIs

• get_prefixed_denom
• get_all_prefixed_denoms
• set_prefixed_denom
• is_account_blocked
• set_port: we had get_port but wasn’t offering an interface for setting it

Some API adjustment

The is_send_enabled and is_receive_enabled methods were returning a boolean whose sole purpose was to propagate errors. This does not correspond with Rust's error-handling convention and against the Result type mean. It was suitable, as long as no specific error reporting was required

More consistent naming

• Consolidate some namings in some places, we were using address and others account for the variable/method names that are related to AccountId type.
• There were still places not adapted to our naming conventions

Refactor the return type of process_recv_packet_execute

I came up with an idea to simplify the return type to the Result<ModuleExtras, TokenTransferError>, to make it easier to understand and implement new changes.

Changes around hash function

Hash function moved to utils since it isn't called only by commitments. Furthermore, the return type of the hasher function has been changed to the [u8;32] type for a fix-sized and more solid type. The same proposal looks applicable for CommitmentRoot, CommitmentProofBytes, and CommitmentPrefix to improve security matters, IMO.

The above matters have been opened as issues (#506, #507, #508, #509) to be included in the changelog.
we could even split the PRs to make things smoother, but I am concerned about merge conflicts. The places they touch are mostly related.
