f4de00d8b5 examples: boids: use std.log.info instead of std.debug.print 
std.debug.print uses IO which depends on file system and thus needs
support from OS, which dont have in freestanding targets (like WASM).

2b994d6b24 gpu: Fix build in 32-bit platforms 
Because of the use of u64, this currently fails to build in 32-bit
platforms like wasm. usize is platform dependent but safe enough for
most use cases.

7486b0ebea mach: Implement key input handling as event loop 
This commit changes the former callback based design to handle key input
(GLFW-like) to an event loop based design (SDL-like). This uses a
TailQueue to store the events from inside of standard glfw callbacks.
This Queue is then popped while polling, thereby emulating event loop.

Removes from Engine the function: ``setKeyCallback`` and adds the
function: ``pollEvent`` which may return an event or null.

This change was done for two reasons:
1) Removing dependence of Engine on App. This was a circular dependency
   and a genuine bad design.
2) Solve the recent regression due to the same which was (i) preventing
   using types declared in Engine.zig and (ii) preventing usage of
   multiple source files in an application.

Currently only key press and release events are implemented as these are
the ones currently used in examples.

3bb45c75a1 mach: introduce cross platform Timer abstraction 
This Timer uses std.time.Timer as backing timer in native platforms, and
will use custom timers for special platforms (wasm, android?, ios?).

Unlike std.time.Timer, its primary API is focused on floats. Also meant
to provides some convenient functions alongside base ones.

Follows std.time.Timer API, but methods by default return f32 i.e
non-precise variant with precise variants available returning u64.

e1192877c3 build: compile examples and applications on demand 
Without this change, anytime a dependency is modified, all the examples
and applications are rebuilt before tring to run any of them. The
problem with this approach is that it leads to long compile times which
will keep on increasing as more and more examples are added.
