Reduce bundle size

[belgattitude]

Reduce bundle size by using class names rather than strings

Importing all exceptions (excluding utilities, typeguards...) now top at 1Kb

Example based on ESM (min+gzip)

Scenario	Size
one exception	450b
all exceptions	< 1kb
everything (typeguards,...)	1.7kb

  ESM (import everything *)
  Package size is 32 B less than limit
  Size limit: 1.76 kB
  Size:       1.73 kB with all dependencies, minified and gzipped
  
  ESM (only HttpException exception)
  Package size is 1 B less than limit
  Size limit: 395 B
  Size:       394 B with all dependencies, minified and gzipped
  
  ESM (only HttpNotFound exception)
  Package size is 2 B less than limit
  Size limit: 455 B
  Size:       453 B with all dependencies, minified and gzipped
  
  ESM (two client exceptions: HttpNotFound + HttpRequestTimeout)
  Package size is 1 B less than limit
  Size limit: 485 B
  Size:       484 B with all dependencies, minified and gzipped
  
  ESM (only isHttpException)
  Package size is 1 B less than limit
  Size limit: 400 B
  Size:       399 B with all dependencies, minified and gzipped
  
  ESM (only createHttpException)
  Package size is 1 B less than limit
  Size limit: 900 B
  Size:       899 B with all dependencies, minified and gzipped
  
  ESM ({ toJson })
  Package size is 1 B less than limit
  Size limit: 805 B
  Size:       804 B with all dependencies, minified and gzipped
  
  ESM ({ fromJson })
  Package size is 635 B less than limit
  Size limit: 2 kB
  Size:       1.36 kB with all dependencies, minified and gzipped
  
  CJS (require everything *)
  Package size is 32 B less than limit
  Size limit: 2.3 kB
  Size:       2.27 kB with all dependencies, minified and gzipped
  
  CJS (only isHttpException)
  Package size is 2 B less than limit
  Size limit: 1.35 kB
  Size:       1.35 kB with all dependencies, minified and gzipped
