shader_ir: Unify constant buffer offset values

hwopus: Implement DecodeInterleaved (the newest variant)

gl_rasterizer: Workaround invalid zeta clears

kernel: Remove the Timer class

video_core: Remove unused Fill related code

A holdover from citra, the Horizon kernel on the switch has no
prominent kernel object that functions as a timer. At least not
to the degree of sophistication that this class provided.

As such, this can be removed entirely. This class also wasn't used at
all in any meaningful way within the core, so this was just code sitting
around doing nothing. This also allows removing a few things from the
main KernelCore class that allows it to use slightly less resources
overall (though very minor and not anything really noticeable).

service: Update function tables

kernel/wait_object: Devirtualize functions related to manipulating the thread list directly

service/nvflinger: Minor renaming changes

Add missing environment variables to travis-ci.env

No inheritors of the WaitObject class actually make use of their own
implementations of these functions, so they can be made non-virtual.

It's also kind of sketchy to allow overriding how the threads get added
to the list anyways, given the kernel itself on the actual hardware
doesn't seem to customize based off this.

This implementation just calls the base class variant of the function,
so this isn't necessary.

This just calls the base variant of the function, so it can be removed.

video_core/dma_pusher: Silence C4828 warnings

This was previously causing:

warning C4828: The file contains a character starting at offset 0xa33
that is illegal in the current source character set (codepage 65001).

warnings on Windows when compiling yuzu.

Add more info into textures' object labels

This functions almost identically to DecodeInterleavedWithPerfOld,
however this function also has the ability to reset the decoder context.

This is documented as a potentially desirable thing in the libopus
manual in some circumstances as it says for the OPUS_RESET_STATE ctl:

"This should be called when switching streams in order to prevent the
back to back decoding from giving different result from one at a time
decoding."

This member function doesn't actually modify instance state, so it can
be const-qualified.

This more accurately describes what the function is actually attempting
to do (it's not a simple trivial getter).

Constant buffer values on the shader IR were using different offsets if
the access direct or indirect. cbuf34 has a non-multiplied offset while
cbuf36 does. On shader decoding this commit multiplies it by four on
cbuf34 queries.

Keeps the logic in one spot for use by both functions.

This doesn't really offer anything over the use of a direct pointer, so
we can just use that instead.

Makes non-mutable state more explicit.
