refactor: rename InternalModuleLoader to ExtModuleLoader, use ext: scheme for snapshotted modules (#18041)
This commit renames "deno_core::InternalModuleLoader" to
"ExtModuleLoader" and changes the specifiers used by the 
modules loaded from this loader to "ext:".

"internal:" scheme was really ambiguous and it's more characters than
"ext:", which should result in slightly smaller snapshot size.

/**
* Write `buffer` to the file specified by `fd`. If `buffer` is a normal object, it
* must have an own `toString` function property.
*
* `offset` determines the part of the buffer to be written, and `length` is
* an integer specifying the number of bytes to write.
*
* `position` refers to the offset from the beginning of the file where this data
* should be written. If `typeof position !== 'number'`, the data will be written
* at the current position. See [`pwrite(2)`](http://man7.org/linux/man-pages/man2/pwrite.2.html).
*
* The callback will be given three arguments `(err, bytesWritten, buffer)` where`bytesWritten` specifies how many _bytes_ were written from `buffer`.
*
* If this method is invoked as its `util.promisify()` ed version, it returns
* a promise for an `Object` with `bytesWritten` and `buffer` properties.
*
* It is unsafe to use `fs.write()` multiple times on the same file without waiting
* for the callback. For this scenario, {@link createWriteStream} is
* recommended.
*
* On Linux, positional writes don't work when the file is opened in append mode.
* The kernel ignores the position argument and always appends the data to
* the end of the file.
* @since v0.0.2
