[LICENSE] [v1.x] Change intgemm to a submodule instead of fetch.

[kpuatamazon]

Description

This resolves the issue that LICENSE referred to 3rdparty/intgemm/LICENSE which was not present in the source because it was downloaded:

https://lists.apache.org/thread.html/r669576b6506f67ea96e9b1bd385b04f59c4e6e7fa1b13a6dc0abc7d9%40%3Cgeneral.incubator.apache.org%3E

Checklist

• Changes are complete (i.e. I finished coding on this PR)
• All changes have test coverage
• Code is well-documented

Changes

• Remove fetch from CMakeLists.txt

Hey @kpuatamazon , Thanks for submitting the PR
All tests are already queued to run once. If tests fail, you can trigger one or more tests again with the following commands:

• To trigger all jobs: @mxnet-bot run ci [all]
• To trigger specific jobs: @mxnet-bot run ci [job1, job2]

---

CI supported jobs: [edge, windows-gpu, unix-gpu, windows-cpu, clang, sanity, unix-cpu, miscellaneous, website, centos-cpu, centos-gpu]

---

Note:
Only following 3 categories can trigger CI :PR Author, MXNet Committer, Jenkins Admin.
All CI tests must pass before the PR can be merged.

@mxnet-bot run ci [unix-cpu, unix-gpu]

Testing is really flaky today https://jenkins.mxnet-ci.amazon-ml.com/blue/organizations/jenkins/mxnet-validation%2Funix-cpu/detail/PR-19407/1/pipeline
