Adding the missing quantized-type support in the ODS

[sdasgup3]

Some of the stablehlo ops does not have support for quantized types in their tablegen specification, prohibits writing StableHLO quantized programs using those ops. The PR is about adding the missing support for the following ops. Also, I believe the ongoing specification work, should not deviate much from the proposed changes here.

stablehlo.atan2
stablehlo.divide
stablehlo.power
stablehlo.remainder
stablehlo.subtract

stablehlo.abs
stablehlo.cbrt
stablehlo.cosine
stablehlo.exponential
stablehlo.exponential_minus_one
stablehlo.log
stablehlo.log_plus_one
stablehlo.logistic
stablehlo.negate
stablehlo.rsqrt
stablehlo.sign
stablehlo.sine
stablehlo.sqrt
stablehlo.tanh

stablehlo.cholesky
stablehlo.triangular_solve

Other than these ops, we have fft, rng, and rng_bit_generator (or something else which I might be missing) which could be potential candidates for the support. I propose that we add the support after adding the specification of those op as adding the support might need some non-trivial discussion.

This may need some VHLO changes to preserve forward compatibility. Will take a closer look shortly.

Per #1652, quantization is an unspecced feature and therefore there are no compatibility guarantees regarding changes to these features. Good to proceed.
