fix(input): autosize width not updated when value changed from outside

[c01dwave]

Description

Fix #7269

When using type="text" input with autosize prop, if the bound value is modified externally (e.g., from another textarea sharing the same v-model), the input width does not update accordingly.

Root Cause

The watch logic for syncing mirror only triggered when autosize && type === 'textarea', which excluded type="text" inputs from receiving external value change updates.

Solution

Remove the type === 'textarea' condition so that all autosize inputs (both text and textarea) will sync their dimensions when the value changes from outside.
