[RFC]: add `@stdlib/array/base/count-same-value`

[kgryte]

Description

This RFC proposes adding the package @stdlib/array/base/count-same-value.

The package should be structured similarly to @stdlib/array/base/count-truthy.

The package should expose an API having the same signature as countTruthy, with the addition of a value argument.

function countSameValue( x, value ) {...}

Internally, the package should use @stdlib/assert/is-same-value to test whether an element x[i] is equal to a specified value.

Package: @stdlib/array/base/count-same-value
Alias: countSameValue
