Continue fixing bash scripts
**What this PR does / why we need it**:
This PR continues the work of fixing bugs in shell scripts (see https://github.com/kubernetes/kubernetes/pull/59572 for the previous PR). The fixed scripts are `hack/grab-profiles.sh` and `hack/update-codegen.sh`. Most of the issues are found by using `shellcheck`. The goal is to make the scripts work and behave as they did previously, but fix obvious bugs and make them more robust and resilient for irregular input such as file names with special characters or whitespace in them.
**Which issue(s) this PR fixes** *(optional, in `fixes #<issue number>(, fixes #<issue_number>, ...)` format, will close the issue(s) when PR gets merged)*:

**Special notes for your reviewer**:
**Release note**:
```release-note
NONE
```
Use "find -exec" instead of plain "find | xargs" to fix handling of
difficult file names (such as those containing spaces). Also, use
"mapfile" for creating the array from the output instead of letting the
shell split the results into the array. Add double quotes to places
where variable handling needs it to prevent splitting and globbing.
The current code
if ! [[ " ${INTERNAL_DIRS[@]:-} " =~ " ${int_group} " ]]; then
is broken because the array is concatenated in [[ .. ]] structure. This
means that the match will be done to any substring in the resulting
string which just happens to include ${int_group}. Fix this to use a
loop instead, and do exact matching. Also make tabs consistent in the
for loop.
Use "mapfile" and "read" to split the $KUBE_AVAILABLE_GROUP_VERSIONS
string into an array using space as the delimiter. This prevents shell
from globbing and splitting the string in potentially wrong places.

code-generator: move kube group list out of client-gen
We had a hard-coded group list in the client-gen code for the internal Kubernetes api groups. For the external groups, we collected the actual GVs in update-codegen.sh. This PR does the latter for internal groups as well.
This commit turns on client-gen for k8s.io/metrics. Clients are
generated for `k8s.io/metrics/pkg/apis/metrics` (both internal and
v1alpha1). `k8s.io/metrics/pkg/apis/custom_metrics` uses a bespoke
client due to the unique nature of its paths.
