Add Khmer(km) Locale Support

[seanghay]

Closes #981

I opened an issue a while back, but the issue was temporary closed due to I was not available to do it.

• Khmer language support #981

Now I am again in need of Khmer locale inside date-fns. And I think other people need it too.

If anything doesn't seem right, please let me know. I'll make changes to fit your needs.

Thanks!

Here you go, Bong!
I'm using shadcn-vue in my Nuxt.js project.

<Calendar
          v-model="model"
          :year="selectedYear"
          :month="selectedMonth + 1"
          initial-focus
          class="p-0"
          locale="km-KH"
        />

I checked it — they're using date-fns.
I tested it, and it works fine with other languages, but not with Khmer.

1. france (fr-FR)

2. chinese (zh-CN)

3. thai (th-TH)

4. khmer (km-KH) not work.

@Kokleng-Dev Looks like shadcn-vue uses reka-ui uses @internationalized/date which uses Intl.DateTimeFormat (not supported Khmer) not date-fns.
