fix(config): allow LogLevel to work with isolatedModules and update all warns and errors to respect logLevel (#30350)

Issue number: internal

---------

## What is the current behavior?
- `LogLevel` throws error `Error: Cannot access ambient const enums when
'isolatedModules' is enabled`
- Several existing console warns and errors are not calling the function
that respects the `logLevel` config

## What is the new behavior?
- Remove `const` from the `enum` to work with `isolatedModules`
- Update `console.warn`s to `printIonWarning`
- Update `console.error`s to `printIonError`

## Does this introduce a breaking change?
- [ ] Yes
- [x] No

## Other information

Dev build: `8.5.5-dev.11744729748.174bf7e0`
