Problem:  wast filetype should be replaced by wat filetype
Solution: start using the official wat filetype name

runtime: rename `wast` filetype to `wat` (Wasm text format)

The problem is the name of the current filetype wast. When the plugin
was initially created, the file extension for Wasm text format was not
fixed and .wast was more popular.

However, recently .wat became the official file extension for
WebAssembly text (WAT) format and .wast is now a file extension for the
unofficial WAST format, which is a superset of .wat for the convenience
to describe the Wasm specification conformance tests.

https://webassembly.js.org/docs/contrib-wat-vs-wast.html

However for now, let's keep using the `wat` filetype even for the .wast
extension, so that we at least do not lose the filetype settings and
syntax highlighting. This can be adjusted later, if it turns out to have
a separate need for.

runtime(php): Update the php indent script to the 1.75 (from 1.70) (vim/vim#13025)

Changes:

1.75:
- Fix 2072/PHP-Indenting-for-VImvim/vim#87: The indent optimization was causing wrong indentation of lines
  preceded by a line ending with '}' when preceded by non white characters.
- Fix long standing non-reported regex escaping issue in cleaning end of line
  comments function. This should help fixing some other unreported issues when
  parts of codes are commented out at ends of lines...

1.74:
- Fix 2072/PHP-Indenting-for-VImvim/vim#86: Add support for `match` expression.

1.73:
- Fix 2072/PHP-Indenting-for-VImvim/vim#77 where multi line strings and true/false keywords at beginning of a
  line would cause indentation failures.

1.72:
- Fix vim/vimvim/vim#5722 where it was reported that the option PHP_BracesAtCodeLevel
  had not been working for the last 6 years.

1.71:
- Fix 2072/PHP-Indenting-for-VImvim/vim#75 where the indent script would hang on some multi-line quoted strings.
