Metal: Generate names for rewritten inputs
When expanding multi-component fields to multiple single-component
fields, use AngleInternal namespace for the new names. The names are
generated with form "someField_0" where _0 is the component index.
If these are not created in AngleInternal, caller is able to create
a name clash by introducing single-component field "someField_0".
Fixes an assert where the vec4(a_) + vec4(a) would assert on size
mismatch because the variable lookup for "a_" would find a rewritten
variable for the expanded matrix row of "a".
