feat(user-action): add callback function to create custom attributes in user action logs

[ssakhamu]

Which problem is this PR solving?

In other instrumentation packages (navigation, web-vitals, etc), the applyCustomLogRecordData hook allows custom attributes to be attached to logs. This hook does not exist in the user-action instrumentation; this change adds this hook into the user-action instrumentation with the appropriate tests. The goal is to provide consistency in adding custom attributes to any logs generated across instrumentation packages.

Short description of the changes

• adds the applyCustomLogRecordData hook to UserActionInstrumentationConfig
• safely executes this hook on the generated log record in the event of a click
• tests the success and failure cases of the hook

Type of change

Please delete options that are not relevant.

• New feature (non-breaking change which adds functionality)
• This change requires a documentation update

How Has This Been Tested?

Please describe the tests that you ran to verify your changes. Provide instructions so we can reproduce. Please also list any relevant details for your test configuration

• if the applyCustomLogRecordData hook is present in the config passed into UserActionInstrumentation, ensure that the custom attributes it creates are in the log record
• if the applyCustomLogRecordData hook throws an error, ensure that the user action log is still emitted and the error is logged via diagnostics logger

These two tests are in packages/instrumentation/src/user-action/instrumentation.test.ts.
