Turn on ALL perf checks

1st, alphabetize the tidy-list for good housekeeping.

Next, enable all the clang-tidy performance checks, and resolve all the
issues.  most of the issues boil down to:
1. Using std::move on const variables.  This does nothing.
2. Passing big variables (like std::string) by value.
3. Using double quotes on a find call, which constructs an intermediate
string, rather than using the character overload.

Tested
Loaded on system, logged in successfully and pulled down webui-vue.  No
new errors.

Walked the Redfish tree a bit, and observed no new problems.

Ran redfish service validator.  Got no new failures (although there are
a lot of log service deprecation warnings that we should look at).
