VideoCommon: fix clang version check

That was... er... a typo!
VideoCommon: make version check easier to read
DolphinWX: Remove the use of some wx 1.0 compatibility functions.

Uses the recommended replacements.
DolphinWX: Remove two c_str calls in ISOProperties.cpp.
OGL: Correctly guard against array bounds of s_encodingPrograms

s_encodingPrograms is defined as an array with a length of 64
NUM_ENCODING_PROGRAMS is also defined as 64.

However 64 is out of bounds, so we want to be comparing for "equal to or
greater than here"

Brings it more in-line with the rest of the codebase.
