Add optional param hex to getTransaction and getBlock.

[Muhammad-Altabba]

Description

Fixes #5761 and #5703 by adding an optional parameter hex for both getTransaction and getBlock.
However, another optional bigIntOnOverflow has been added at hexToNumber and toNumber only. Which introduces a functionality similar to 4.x for those 2 functions only.
