fix: only do type checking while compiling file

[ahnpnl]

closes #1470
revert #1472 and #1450

Background
In #1450 , we moved the type checking part to getCacheKey. However, this cost performance because ts compiler will do extra diagnostics check and cache them for files which are not the wanted-compiled files.

Changes
This PR does several things:

• Move the type checking back to compiling logic. By putting in compiling logic, we only do diagnostics check and cache them for wanted-compiled files. So we don't need also the workaround in fix(config): set default outDir to $$ts-jest when allowJs is enabled without outDir #1472
• Introduce caching to file system for imported modules' path of test files. By reading this cache whejn creating compiler and fetch into memory cache, we can solve With cached results, changes to type definitions are not detected #1390
• Add e2e tests for With cached results, changes to type definitions are not detected #1390

Caveat
There will be a slight decrease in performance since we need to do extra diagnostics check not only for test file which has changed imported modules but also the changed module to solve #1390
