  [mlir][emitc] Refactor the e2e test for TOSA -> EmitC lowering (#194686)

Update the TOSA -> EmitC test, mlir/test/Dialect/EmitC/tosa/ops.mlir, to also
compile the generated source with a C++ compiler. This adds an `mlir-translate`
step, making the overall flow:

    mlir-opt tosa.mlir | mlir-translate | c++ -Wall -Werror -c

Although the test still does not execute the generated code, compiling it with
a host compiler increases coverage and makes the test closer to an integration
test. For this reason, move it to:

    mlir/test/Integration/Dialect/EmitC/

The source generated by the translator uses `size_t`, which requires the
`stddef.h` header. This is currently provided explicitly in the compile step
with `-include stddef.h`; a follow-up should consider emitting the required
include from the translator instead.
