Add unmeasurable variance kind for marking types whose variance result is unreliable (#30416) 
* Add unmeasurable variance kind for marking types whose variance result is unreliable

* Remove now-unneeded nongeneric checks

* Add rule allowing `Readonly<any>` to be `any` instead of `{readonly [index: string]: any}`

* All Unmeasurable variances to still shortcut structural comparisons in some cases

* Separate unmeasurable from unreliable to reduce the impact of this change, for now

* Fix lint

* Remove Readonly<any> -> any callout

* Add fix for circularity error triggered by deep signature return type comparisons with `this` types

d934401265 Change the type of 'uriComponent' (passed to 'encodeURIComponent') from 'string' to 'string | number | boolean'. Fixes #18159 (#31103) 
- According to the ECMAScript 5.1 spec (§15.1.3.4), 'encodeURIComponent' invokes the abstract operation 'ToString': https://www.ecma-international.org/ecma-262/5.1/#sec-15.1.3.4
- In the spec (§9.8), 'ToString' accepts an 'Undefined', 'Null', 'Boolean', 'Number', 'String' or 'Object' argument: https://www.ecma-international.org/ecma-262/5.1/#sec-9.8
- TypeScript’s 'StringConstructor' accepts an argument with type 'any': b0100100a1/lib/lib.es5.d.ts (L518)

f9d12ed54b fix 31012 allow noEmitOnError with isolatedModules (#34) (#31043) 
fix #31012

Since the purpose of isolatedModules: true is to
do extra validation to ensure that separate
compilation is safe

Allowing emit in the presence of errors is
compatible with that intention.
