bench: benchmark transaction creation process

Browse Source 
Goal 1:
Benchmark the transaction creation process for pre-selected-inputs only.
Setting `m_allow_other_inputs=false` to disallow the wallet to include coins automatically.

Goal 2:
Benchmark the transaction creation process for pre-selected-inputs and coin selection.

-----------------------

Benchmark Setup:
1) Generates a 5k blockchain, loading the wallet with 5k transactions with two outputs each.
2) Fetch 4 random UTXO from the wallet's available coins and pre-select them as inputs inside CoinControl.

Benchmark (Goal 1):
Call `CreateTransaction` providing the coin control, who has set `m_allow_other_inputs=false` and
the manually selected coins.

Benchmark (Goal 2):
Call `CreateTransaction` providing the coin control, who has set `m_allow_other_inputs=true` and
the manually selected coins.
