feat: implement intrinsic function BOOLEAN-OF-INTEGER

[kmr-srbh]

Specification

BOOLEAN-OF-INTEGER returns a boolean item of usage bit representing the binary value
of argument-1. argument-2 specifies the length of the boolean data item that is returned.

argument-1 must be a positive integer.
argument-2 must be a positive non-zero integer

Returned value is a boolean item of usage bit that has the same bit configuration as
the binary representation of the value of argument-1, where the rightmost boolean position
is the low-order binary digit. The boolean value is zero-filled or truncated on the left, if
necessary, in order to return a boolean item whose length is specified by argument-2 in
terms of boolean positions.

As discussed with @GitMensch, the changes in this PR need to be added as an enhancement over the implementation of BIT-OF intrinsic, which does the same work as BOOLEAN-OF-INTEGER, but on alphanumeric literals considering full byte lengths instead of N bits. Marking this PR as draft for now.
