JS-372 Introduce caches to improve SonarLint performance

[zglicz]

As part of this improvement, we include:

1. TsConfigCache <- special cache for SonarLint runtime. It supports 2 levels of caching, of the file system traversal to detect tsconfigs and consequently a cache for a filename to tsconfig mapping. It is generous with the clearing of the cache whenever, a tsconfig is modified or a new project file (javascript or typescript) is created.
2. Optimization of the filename to tsconfig search, by reordering pending tsconfigs to process the most likely tsconfig first.
3. Removing superfluous calls to Path.realPath() when receiving filenames from the Typescript compiler and later when matching files to tsconfig. For SonarJS, this proved important to reduce querying all tsconfigs (195 configs) found in SonarJS from 20s to 3s.

LGTM! just a couple of minor things I'm having questions about

[vdiez]

why did we remove this?
