eqv, eq, fill for ivec2 and ivec3, new print functions for ivec2 and ivec4, documentation fixes

[duarm]

• New glm_ivec4_print, glm_ivec2_print functions
• New eqv, eq, fill functions for ivec3 and ivec2
• Adding missing glm_vec2_print to the docs.
• Adding missing call func glmc_vec2_fill, glmc_vec2_eq, glmc_vec2_eqv
• Changed wording on the print documention to a generic "vector" and "matrix" instead of the type, to be more inline with how it's worded everywhere else.

@duarm the PR is merged, thanks for your contributions 🚀 It would be nice to have ivec4 versions of the new functions :)

Would it be possible to update glm_ivec2_fill and glm_ivec3_fill to explicitly cast those values? For example, compiling with MSVC /W2 (or above) will throw:

cglm\include\cglm\ivec2.h(219,17): warning C4244: '=': conversion from 'float' to 'int', possible loss of data 
cglm\include\cglm\ivec3.h(227,24): warning C4244: '=': conversion from 'float' to 'int', possible loss of data

@gottfriedleibniz wow my mistake, those parameters must be int as base type of vector, it is fixed at: 126f809

If that's the case, glmc_ivec{2,3}_fill also require updating.

done :)

missed that too, sorry
