Replace axios with built-in alternatives

### Describe the feature

Can use of axios be replaced by native node:http(s), fetch, or XMLHttpRequest?

### Use Case

Because this package (aws-crt) is a dependency of the AWS SDK for JavaScript (v3), SDK users are affected by recurrent vulnerabilities discovered in the axios package.

Although it is ranged `^1.x`, applications may not update with as much frequency as would be required.

Secondarily, it would also reduce the package size to remove this dependency.

- [ ] This feature might incur a breaking change

The issue does not name any files, tests, or entry points. Start by locating the axios dependency and every usage in the repository, then trace the related request paths and tests. Done means axios is no longer required while the existing behavior remains covered by the relevant test suite.
