ref(build): Turn on isolatedModules TS option (#4896)

Note: This and #4926 are together a (slightly updated) repeat of #4497, to get it onto the main v7 branch.

This applies [the TypeScript `isolatedModules` setting[1] to all packages in the repo, which is necessary in order for us to use any compiler other than `tsc`. (All other compilers handle each file separately, without understanding the relationships between them the way `tsc` does, so we need TS to warn us if we're doing anything which would make that a problem).

It also makes the second of two code changes necessary in order to be compatible with the `isolatedModules` flag: all re-exported types and interfaces (anything that will get stripped away when compiling from TS to JS) are now exported using `export type`. This lets non-`tsc` compilers know that the exported types are eligible for stripping, in spite of the fact that said compilers can't follow the export path backwards to see the types' implementation.

(The other code change, eliminating our usage of the `Severity` enum, was split off into the PR linked above.)
