Merge master/2.0.8 into 2.1.0 (#551)

* Imminent fixes for bugs found on master branch (#512)

* The vanilla level checks define for Yoshi is inverted, causing him to require 120 stars when it is off and appear at 0 stars when it's on

*  The downwarp fix results in Mario levitating in midair when grabbing Bowser midair. While downwarps should still be fixed, the change should be reverted immediately until a better fix is made.

*  Some checks of Mario's floor class were using the wrong defines, which can lead to unexpected behavior in the event anyone wants to reorder surface types. By default the SURFACE_CLASS_SLIPPERY and SURFACE_SLIPPERY defines have the same value, which is why this mistake is hard to notice.

*  The firsty frames define was implemented poorly, not allowing for vanilla firsty behavior no matter what the values were set to. This has been reverted, while avoiding the UB in the original vanilla code.

*  Removed the ledge grab changes that fix QSLGs and change the false ledgegrab define since Arceveti wanted to in his PR

* Update version to 2.0.4 (#515)

* HackerSM64 2.0.5 (#517)

* Bugfix: race condition with accessing cleared audio memory pools

* Bugfix: skyboxes access tiles out of range when looking straight down (#518)

* Vscode fixes (#516)

* Revert s32 angles and remove Angle typedef usage (#529)

* Fix some surface shadowing (#531)

* Delete rtc.h

* Remove `wait_for_audio_frames()`
