TypeScript: support for "properties:static"

[jafl]

Support for properties:static, like what I added to the JavaScript parser

This is a variable so TsFields is better than sFields.

I'll merge after finishing #4271.

@jafl could you add

	def->versionCurrent = 1;
	def->versionAge = 1;

As you did in jscript.c?

    TypeScript: support for "properties:static"

commit 0644fb80a8250cc3ca6ba00037e490768fe4492e (tag: p6.2.20250615.0)

Your change based on too old source tree.
Could you do something like:

git checkout master
git pull upstream master:master
git checkout typescript-static-property
git rebase master
git push --force origin typescript-static-property

[jafl]

I need to open a new PR, because I rebased.

[masatake]

(You can use push --force just after rebasing.)
