Centralize tools build target's references

Mostly, this reduces references to `src/utilities.ts`, which will come in handy later.
Introduce new `base` TypeScript build target combining all utilities/services

... and include it's `d.ts` output in the other build targets' references files. Reduces compile time of, e.g., `grunt player` by about 20%.
Move all files included in the `base` build target into `src/base` and combine them during building
Combine files in the `tools` build target into one output file and reference the resulting d.ts file in other build targets
Combine files in the `swf` build target into one output file and reference the resulting d.ts file in other build targets
Combine files in the `avm2` build target into one output file and reference the resulting d.ts file in other build targets
Combine files in the `avm1` and `avm1lib` tsc build targets into one build target and output file and reference the resulting d.ts file in other build targets

To make this work, I had to untangle the dependencies between `flash` and `avm1lib`: they're now both using `d.ts` files for the few members of the respective other build target that they really depend on.
Combine files in the `gfx` build target into one output file and reference the resulting d.ts file in other build targets
Combine files in the `flash` build target into one output file and reference the resulting d.ts file in other build targets

Combines several hundred output files into one.
Update `shu` build target to build all required targets in order to get a working player

Plus bits and pieces that needed fixing.
