In `@pkg/asset/installconfig/aws/instancetypes.go`:
- Line 46: Update getInstanceType so the EC2 describe filter performs an exact
match for the configured instance type, preventing wildcard results from being
treated as the requested value; alternatively use InstanceTypes for literal
lookups and verify the returned InstanceType matches. Add a regression test
covering a wildcard such as r7* and confirming it is not accepted as an exact
configured type.

Look up only the instance types referenced by the install config and cache the results, rather than paginating over every type in the region.
Provide an httpmock-backed client returning an empty DescribeInstanceTypes response so unknown types resolve to not-found instead of attempting a live EC2 call.

Description
This PR updates the installer to lazily look up only the instance types referenced by the install config and cache the results, rather than paginating over every type in the region.
Why: If an explicit type is defined in the install-config, there's a noticeable delay during install where the install paginates through all the available type. As AWS introduces more types, this list will just keep growing, making install slower (in CI).
Let's see if this help 👀
