fix(native): Remove key_sampling_percent from native Sql invoked functions and Advance velox

[pramodsatya]

Description

key_sampling_percent is now a built-in function in Velox (ref: facebookincubator/velox#16113), it should no longer be registered as a native sql invoked function.

Motivation and Context

Fixes tests error seen during submodule update:

[2026-02-25T09:45:52.123Z] Caused by: java.lang.RuntimeException: line 1:8: Function 'native.default.key_sampling_percent' has two matching signatures. Please specify parameter types. 
[2026-02-25T09:45:52.123Z] First match : 'native.default.key_sampling_percent(varchar):double', Second match: 'native.default.key_sampling_percent(varchar):double'

The same error also appears to have impacted #27193.

== NO RELEASE NOTE ==
