Change RSQRT precision to 2 ulp to allow
unfused square root and reciprocal.
Also fixes:
- a typo in EXP and POW conformance
- exp2() handling of large negative values
- symmetry about 0 of test set S=4 data generation
- err_bnd cannot be negative
- ulp not taken for reference value of 0

EXP and POW are complex to implement in a precise number of ulp
and a more flexible precision is given.
Additionally, the test generater S=5 has the bias values
changed to zero. If the bias values are non-zero then a
bias for all output tensor elements of the channel can affect
the dot product bias test.
The numeric accuracy helpers are updated for bf16.

Integer inputs and outputs to TOSA operators are now defined as signless
values. In most instances the operator will used signed arithmetic as
indicated in previous versions of the specification resulting in little
functional change to the specification.
New attributes have been added to the RESCALE operator to indicate
whether the input and output values should be treated as signed or unsigned.
Explicit use of static_cast, sign_extend, zero_extend and truncate are added
to the pseudocode to avoid ambiguity.

Shape inference derives the shape of tensors in
the graph from input shapes. Operations such as RESHAPE
may need calculations to derive the new tensor shape.
This patch:
- Adds a DIM operator to get the size of a tensor in
a given axis as a rank 0 tensor of type shape_t
- Allows RESHAPE to take a 1D shape tensor as input for
the new shape
- Allows RESIZE, TILE, PAD to take input sizes based
on shape tensors.
- Allows ADD, SUB, MUL, INTDIV to operate on rank 0
shape_t tensors
- Allows CONCAT to concatenate 0D shape_t tensors to
a 1D shape_t tensor
- Adds CONST support for shape_t tensors
In this version of the specification shape tensors must
be resolvable to constants at backend compile time.

For an operation that performs broadcast the
output shape size must be the maximum of the input shape
sizes in each dimension.
Additionally, the input dimension size must be 1 whenever
an input shape does not match the output shape size
in a dimension.

We can't easily spell check the entire specification, the
pseudocode and operator tables make it unworkable. This
adds a simple python script that tries to extract just the
description of the operators for checking. It also does a check
over the entire license.
A custom dictionary is used to contain specification custom words.
