FOV and Block Speed Toggle Config (1.21)

[SakuraKitsurugi]

What

Adds 2 configs:

1. Allows players to disable FOV changes from blocks that modify player speed.
2. Allows players to disable speed change from blocks that modify player speed.

Implementation Details

• Readded @YoungOnionMC's Concrete Block FOV speed code and modified it to not break due to null .get.
• Added one client and one gameplay config in ConfigHolder.java
• Added an early return in playerTickEvent(TickEvent.PlayerTickEvent event)
• Added a config check in getValueWithoutWalkingBoost(AttributeInstance attrib) that sets FOV to normal as it forces BLOCK_SPEED_BOOST to be included in the calculations.

How Was This Tested

• Tested in runClient, sorry for the long video: https://cdn.kitsuryuki.net/Videos/gtceu_config_video_1_21.mp4
