[NFC][Linalg] Add `matchConvolutionOpOfType` API and make `isaConvolutionOpOfType` API a wrapper (#174722)

-- This commit involves the following updates pertaining to
`isaConvolutionOpOfType` API :-
1. We don't want dilations/strides of convolution op to be returned as
pointer arguments to the API function - to tackle this we create a new
API `matchConvolutionOpOfType` which would return an optional struct of
dilations/stride.
2. To not break the original API's use case as a simple querying
functionality with true/false return - we keep `isaConvolutionOpOfType`
as a wrapper API which will invoke `matchConvolutionOpOfType` API and
return true/false depending on whether `matchConvolutionOpOfType` API
returned any value or not.
3. Dilations/strides of named convolution op are also populated now (it
was missed in the previous PRs while creating `isaConvolutionOpOfType`).
4. [Max/Min]UnsignedPool ops' body matcher now only matches unsigned int
ops (refer: https://github.com/llvm/llvm-project/pull/166070)

-- No tests are being added as all the above are NFC changes around the
API which already is being tested via Specialize.cpp.
