Update on "[ET-VK][ez] Use standard quant naming scheme for quantized ops"

## Context

Use standard naming scheme for quantized operators introduced in the previous PR.

For weight only quantized linear operators, the names introduced are:

`linear_qcsnw`:

* q - quantized
* c - per-channel / channelswise
* s - symmetric
* n - number of bits (qcs4w for 4-bit quant, qcs8w for 8-bit quant)
* w - weight quantized

`linear_qga4w`:

* q - quantized
* g - per-group / groupwise
* a - affine
* 4 - quantized to 4 bits
* w - weight quantized

## Changes

Rename instances of `q_8w_linear` to `linear_qcs8w` or `linear_qcsnw`.

Rename instances of `q_4w_linear` to `linear_qga4w`.

Rename cpp files to match the new naming convention.
