feat: no type-check by default (#14691)

This commit changes default default behavior of type checking
for several subcommands.

Instead of type checking and reporting type errors only for local
files, the type checking is skipped entirely. Type checking can
still be enabled using the "--check" flag.

Following subcomands are affected:
- deno cache
- deno install
- deno eval
- deno run
