Fix bugs and UB in bit shifting ops (#13663)
# Description
Fixes #11267

Shifting by a `shift >= num_bits` is undefined in the underlying
operation. Previously we also had an overflow on negative shifts for the
operators `bit-shl` and `bit-shr`
Furthermore I found a severe bug in the implementation of shifting of
`binary` data with the commands `bits shl` and `bits shr`, this
categorically produced incorrect results with shifts that were not
`shift % 4 == 0`. `bits shr` also was able to produce outputs with
different size to the input if the shift was exceeding the length of the
input data by more than a byte.

# User-Facing Changes
It is now an error trying to shift by more than the available bits with:
- `bit-shl` operator
- `bit-shr` operator
- command `bits shl`
- command `bits shr`

# Tests + Formatting
Added testing for all relevant cases
